FOSSIL FISHES, AMPHIBIANS, REPTILES, BIRDS, AND MAMMALS.

Vertebrates.—

The above-named classes of animals are distinguished from those previously dealt with, by the presence of a vertebral column. The vertebral axis may be either cartilaginous as in some fishes, or bony as in the greater number of animals belonging to this sub-kingdom.

Chordata.—

LINKS BETWEEN THE INVERTEBRATES AND FISHES.—The curious little ascidians or “sea-squirts,” belonging to the group Tunicata, are held by some authorities to be the degenerate descendants of a free-swimming animal having a complete notochord and nerve-tube, structures which are now only seen in the tails of their tadpole-like larvae. The fully developed tunicate is generally sessile and provided with a thick outer coat (tunic) and muscular inner lining. This outer coat in some forms, as Leptoclinum, is strengthened with tiny calcareous spicules, and these are sometimes found in the fossil state in Cainozoic clays, as well as in some of the calcareous deep-sea oozes. The little stellate spicules of Leptoclinum are abundant in the Balcombian clays of Mornington, Victoria.

Another primitive form with a notochord is the Lancelet, but this, having no hard parts, is not found in the fossil state.

Primitive Types of Fishes.—

FISHES.—The remains of fishes are naturally more abundant in the fossil condition, owing to their aquatic habits, than those of other vertebrates. The earliest fishes were probably entirely cartilaginous, and some have left only a mere trace or impression on the rocks in which they were embedded. These primitive fishes have no lower jaw, and are without paired limbs. They are sometimes placed in a class by themselves (AGNATHA). The orders of this primitive fish series as represented in Australasia are the Osteostraci (“bony shells”), of which the remains of the Cephalaspis-like head-shield of Thyestes has been found in the Silurian of N.E. Gippsland, Victoria (Fig. 122); and the Antiarchi, with its many-plated cuirass, armoured body-appendages, internal bony tissue, and coarsely tuberculated exterior, as seen in Asterolepis australis, a fossil occasionally found in the Middle Devonian Limestone of Buchan, Gippsland.

True Fishes.—Devonian.—

Of the true fishes (Pisces), the Elasmobranchii (“slit-gills”), a sub-class to which the modern sharks belong, are represented in the Devonian series by the paired spines of a form resembling Climatius, found both in Victoria and New South Wales. Remains of Dipnoi (“double-breather” or lung-fishes) occur in the Devonian of Barker Gorge, Western Australia, represented by a new species allied to Coccosteus (“berry-bone” fish); and in a bed of the same age at the Murrumbidgee River, New South Wales by the cranial buckler of Ganorhynchus sÜssmilchi.

Carboniferous Fishes.—

The Lower Carboniferous sandstone of Burnt Creek and other localities near Mansfield, Victoria, contains an abundant fish fauna, associated with stems of Lepidodendron. The slabs of sandstone are often ripple-marked and show signs of tracks and castings of shore-living animals. These deposits were probably laid down in shallow water at the shore margin or in salt lagoons or brackish areas skirting the coast, into which at intervals the remains of the giant lycopods were drifted. The more important of these fish remains are Elasmobranchs, as Gyracanthides murrayi (Fig. 123) and Acanthodes australis; the Dipnoan, Ctenodus breviceps; a Rhizodont or fringe-finned ganoid, Strepsodus decipiens (Fig. 124 A); and a genus related to Palaeoniscus, Elonichthys (E. sweeti, Fig. 124 B, and E. gibbus). The defence spines of Gyracanthides are fairly abundant in the sandstones; whilst on some slabs the large enamelled scales of Strepsodus are equally conspicuous.

From the sandstones of the same age, Lower Carboniferous, in the Grampians of Western Victoria, some small but well-preserved spines belonging to the genus Physonemus have been found associated with a new variety of the well-known European Carboniferous brachiopod, Lingula squamiformis (var. borungensis).

Carbopermian Fishes.—

In the Carbopermian (Gympie Beds) of the Rockhampton District, Queensland, a tooth of a Cochliodont (“snail tooth”) occurs, which has been doubtfully referred to the genus Deltodus (? D. australis). The Cochliodontidae show dentition remarkably like that of the Cestracion or Port Jackson Shark. Another tooth having the same family relationship has been referred to Tomodus ? convexus, Agassiz; this is from the Carbopermian of the Port Stephen district of New South Wales. From the Newcastle Coal Measures in New South Wales a Palaeoniscus-like fish, Urosthenes australis has been described.

Carbopermian fish remains are rare in Western Australia. They comprise a wrinkled tooth of Edestus (E. davisii) from the Gascoyne River, belonging to a fish closely related to the Port Jackson shark; and a cochliodont, Poecilodus (P. jonesi, Ag.) from the Kimberley district.

Triassic Fishes.—

Fossil fishes are important and numerous in Australian Triassic beds, especially in New South Wales. At the base of the Hawkesbury or close of the Narrabeen series, the railway ballast quarry near Gosford has yielded an extensive and extremely interesting collection. Near the floor of the quarry there is a band of sandy shale and laminated sandstone 5 feet 9 inches in thickness, and this contains the following genera:—A dipnoan, Gosfordia; and the following ganoids or enamelled scale fishes—Myriolepis, Apateolepis, Dictyopyge, Belonorhynchus, Semionotus, Pristisomus (see antea, Fig. 18), Cleithrolepis (Fig. 125), Pholidophorus and ? Peltopleurus.

Upper Triassic Fishes.—

In the middle of the Wianamatta or Upper Trias Series at St. Peter’s, near Sydney, which contains a fauna described as slightly older in aspect than that of Gosford, having Carbopermian affinities, there occur in the hard shale or clay stone the genera Pleuracanthus (a Palaeozoic shark); Sagenodus (a dipnoan related to Ctenodus of the Victorian Carboniferous); and the following ganoids,—Palaeoniscus, Elonichthys, Myriolepis, Elpisopholis, Platysomus and Acentrophorus. From the soft shales were obtained Palaeoniscus, Semionotus, Cleithrolepis and Pholidophorus; an assemblage of genera somewhat comparable with the Gosford fauna.

Lower Mesozoic Fishes.—

From the Lower Mesozoic sandstone (?Triassic) of Tasmania, two species of Acrolepis have been described, viz., A. hamiltoni and A. tasmanicus. The former occurs in the thick bed of sandstone, of nearly 1,000 feet, at Knocklofty; the latter species in the sandstone with Vertebraria conformably overlying the Carbopermian at Tinderbox Bay.

Jurassic Fishes.—

The Jurassic beds of Victoria contain three genera. Psilichthys selwyni, a doubtful palaeoniscid was described from Carapook, Co. Dundas; whilst Leptolepis, a genus found in the Trias of New South Wales and the Lias and Oolite of Europe, is represented by L. crassicauda from Casterton, associated with the typical Jurassic fern, Taeniopteris. In the Jurassic beds of South Gippsland, at Cape Paterson, an interesting splenial tooth of the mudfish, Ceratodus, was found, named C. avus (Fig. 126). Since then, in a bore-core from Kirrak near the same place a fish scale was discovered (Fig. 127) which, by its shape, size and structure seems to differ in no way from the living lung-fish of Queensland (Fig. 128). It is reasonable to infer that tooth and scale belong to the same species; and in view of the close relationship of the tooth with that of the living mudfish, rather than with that of the Ceratodus found fossil in the Mesozoic of Europe, it may be referred to Neoceratodus, in which genus the living species is now placed.

From the Jurassic beds (Talbragar Series) of New South Wales, an interesting collection of ganoid fishes has been described, comprising Coccolepis australis, Aphnelepis australis, Aetheolepis mirabilis, Archaeomaene tenuis, A. robustus, Leptolepis talbragarensis, L. lowei and L. gregarina (Fig. 129).

Lower Cretaceous Fishes.—

Fish remains are fairly abundant in the Lower Cretaceous of Queensland. They comprise both the sharks and the ganoids. Of the sharks, a specimen, showing seven conjoined vertebrae has been named Lamna daviesii, from the Richmond Downs, Flinders River district; and a tooth referred to Lamna appendiculatus, Agassiz, from Kamileroy, Leichhardt River, N.W. Queensland. The typical Cretaceous genus Corax is represented by a small tooth named C. australis (Fig. 124 C), from the Hamilton River, Queensland, and which closely approaches the tooth of Corax affinis, Agassiz, from the Upper Cretaceous of Europe. Of the ganoid fishes two genera, both members of the family Aspidorhynchidae, have been found in Queensland. Aspidorhynchus sp. and Belonostomus sweeti (Fig. 124 D) have both occurred at Hughenden, Flinders River district. The former genus has a slender body and produced rostrum; in Europe it is more characteristic of Jurassic strata. Belonostomus ranges from the Upper Oolite, Bavaria, to the Upper Cretaceous in other parts of the world. Remains of a species of Portheus, one of the predaceous fishes which lived in the Cretaceous period, consisting of a portion of the cranium with the anterior part of the jaws, has been obtained from the Rolling Downs Formation (Lower Cretaceous) near Hughenden, Queensland.

Cretaceous Fishes, New Zealand.—

The Cretaceous beds of New Zealand are grouped in ascending order as the Waipara Greensands, the Amuri Limestone and the Weka Pass Stone. In the Waipara beds occur the teeth of Notidanus marginalis (Fig. 130 A), and N. dentatus. In the Amuri Limestone N. dentatus is again found, as well as the genus Lamna, represented by L. compressa, Ag. (originally described as L. marginalis, Davis), L. carinata and L. hectori. Two forms of “Elephant fish” are represented by their dental plates, namely Callorhynchus hectori (Fig. 130 B) and Ischyodus thurmanni, Pictet and Campiche (recorded as I. brevirostris, Ag.).

Cainozoic Fishes.—

Fish remains principally consisting of teeth, are common fossils in the Cainozoic beds of southern Australia, particularly in Victoria, and also in New Zealand.

Balcombian Series, Southern Australia.—

The Balcombian beds as seen at Mornington and in the Lower Beds at Muddy Creek, Hamilton, contain the teeth of sharks as Odontaspis contortidens, Lamna crassidens, L. apiculata, Oxyrhina hastalis (rarely), O. minuta, Carcharodon megalodon, and C. robustus.

Janjukian.—

The Janjukian Series (Miocene), represented at Torquay, Waurn Ponds and Table Cape, contains an abundant fish fauna, including amongst sharks, Cestracion cainozoicus, Asteracanthus eocaenicus, Galeocerdo davisi, Carcharoides totuserratus, Odontaspis contortidens, O. incurva, O. cuspidata, Lamna crassidens, L. apiculata (Fig. 130 D), L. compressa, L. bronni, Oxyrhina hastalis (occasional) (Fig. 130 C), O. desori, O. retroflexa, O. minuta, Carcharodon auriculatus (Fig. 130 E), C. megalodon and C. robustus. A species of chimaeroid or Elephant fish is represented by a left mandibular tooth named Ischyodus mortoni, from the Table Cape Beds, Tasmania.

The Corio Bay series contains teeth of Acanthias geelongensis, Sphyrna prisca, Odontaspis contortidens, O. attenuata, Oxyrhina minuta, Carcharodon megalodon, amongst sharks; whilst the spine of a Porcupine Fish, Diodon connewarrensis has been obtained from the clays of Lake Connewarre, Victoria.

Kalimnan.—

The Kalimnan Series is also prolific in the remains of fishes, the principal localities being Beaumaris and Grange Burn, Hamilton. Amongst the sharks there found are, Notidanus jenningsi (related to the Indian Grey Shark), Cestracion cainozoicus (related to the Port Jackson Shark), Asteracanthus eocaenicus, Galeocerdo davisi, G. latidens (Fig. 131 C), G. aduncus, Odontaspis contortidens (Fig. 131 B), O. incurva, O. cuspidata, O. attenuata, Lamna apiculata, L. compressa, Oxyrhina hastalis (abundant), O. desori, O. retroflexa, O. eocaena, O. minuta, Carcharodon auriculatus and C. megalodon. An extinct species of Sting Ray, Myliobatis moorabbinensis (Fig. 131 D), is found at Beaumaris, represented by occasional palatal teeth. Mandibular and palatine teeth of an extinct genus of Elephant Fish, Edaphodon (E. sweeti) are occasionally found at Beaumaris, and at Grange Burn near Hamilton. Two extinct forms of the Wrasse family, the Labridae, are found in Victoria; the pharyngeals of Labrodon confertidens (Fig. 131 E), occurring at Grange Burn, Hamilton, and those of L. depressus, at Beaumaris. The palatal jaws of a Porcupine Fish, Diodon formosus (Fig. 131 F), are frequently met with at the base of the Kalimnan Series, both at Grange Burn and Beaumaris.

Oamaru Series, New Zealand.—

In New Zealand the Oamaru Series, which is comparable in age with the Victorian Janjukian, contains numerous fish remains, chiefly teeth of sharks. These are: Notidanus primigenius, N. marginalis (also occurring in the Waipara Series), Galeocerdo davisi, Odontaspis incurva, O. cuspidata, O. attenuata, Lamna apiculata, L. compressa, Oxyrhina retroflexa, Carcharodon auriculatus, C. megalodon and C. robustus. The teeth of a Sting Ray, Myliobatis plicatilis and of a species of Sea-bream, Sargus laticonus, also occur in this series (Fig. 130 F).

Pleistocene.—

A species of fish belonging to the family of the Perches, Ctenolates avus, has been described from freshwater carbonaceous shale of Pleistocene age from Nimbin on the Richmond River, New South Wales.

Amphibians: Their Structure.—

AMPHIBIANS.—This group includes amongst living forms the Frogs, Toads, Newts, and Salamanders. The remains of amphibia are rare in Australasian rocks, and practically limited to the group of the Triassic Labyrinthodonts. The Amphibia are distinguished from Reptiles by certain changes which their young undergo after leaving the egg. In this intermediate stage they breathe by external gills, these being sometimes retained together with the internal lungs in the adult stage. In the older forms of this group the vertebra is of the nature of a notochord, the joints consisting of a thin bony ring with a gelatinous interior. The Labyrinthodontia have a long, lizard-like body, short pectoral limbs as compared with the pelvic, and five-toed feet. The skull is completely roofed over. The teeth are pointed, with a large pulp cavity and wall of infolded or plicated dentine (hence the name labyrinthodont—maze-tooth). The vertebrae are hollow on both sides, sometimes imperfectly ossified, and with a notochordal canal. Ventral aspect with bony thoracic plates. Cranial bones deeply sculptured, and carrying mucus canals.

Carbopermian Labyrinthodonts.—

The genus Bothriceps, probably an Archegosaurian, is represented by two species, B. australis and B. major from New South Wales (Fig. 132). The latter species occurs in the Oil Shale (Carbopermian) of Airly.

Triassic Labyrinthodonts.—

From the Hawkesbury Series near Gosford, New South Wales, the labyrinthodont, Platyceps wilkinsoni has been described. The skeleton is nearly complete and exposed on the ventral face; the head is 27mm. long and 32mm. broad. This specimen is associated with the remains of ganoid fishes, as Palaeoniscus and Cleithrolepis, together with the equisetum-like plant Phyllotheca.

Other, somewhat doubtful remains having similar affinities to the labyrinthodonts are also recorded from the Wianamatta beds (Upper Trias) at Bowral, New South Wales, consisting of a maxilla with teeth and 11 vertebrae with ribs of the left side. Remains of a labyrinthodont, Biloela, supposed to be related to Mastodonsaurus, have been recorded from the Hawkesbury Series of Cockatoo Island, Port Jackson, New South Wales, by W. J. Stephens, and consisting of a pectoral plate compared by that author with M. robustus (now transferred to the genus Capitosaurus).

The only other recorded remains of this group in Australasia are those noted by W. J. Stephens from the Kaihiku Series (Trias) at Nugget Point, Otago; and in the Otapiri Series (Upper Trias) of the Wairoa district, New Zealand.

Reptilia: Their Structure.—

REPTILIA.—The Reptiles are cold-blooded, vertebrated animals, with a scaly skin or armour. Their respiration is essentially by means of lungs, and they are terrestrial or aquatic in habit. The skeleton is completely ossified (bony). Reptiles, although resembling amphibians externally, are more differentiated in structure and of generally larger proportions. They exhibit great diversity of form, especially as regards their extremities. They were even adapted for flying, as in the Pterosaurs (“Flying Dragons”) with their membranous wing attached to the anterior limb. The Deinosaurs (“Terrible Reptiles”) were often of great size, exceeding the dimensions of any land mammals, and their limbs were adapted for walking. The marine reptiles, as the Ichthyosauria (“Fish-lizards”) and Sauropterygia (“lizard-finned”) had the limbs transformed into paddles. The neural spines in the vertebra of the Turtles are laterally expanded into a carapace and united with dermal plates. The vertebrae of Reptilia show great variation of form, being biplanate (amphiplatyan), biconcave (amphicoelus), hollow in front (procoelus), or hollow at the back (opisthocoelus). In the case of Reptiles having both pairs of limbs developed, the cervical, dorsal, sacral and caudal regions may be separately distinguished. Amongst the Ophidia (Snakes), Pythonomorpha (“Sea-lizards”) and Ichthyosaurs (“Fish-lizards”) there is no differentiated sacral region. The skull of the Reptiles is nearer that of Birds than Amphibians. The basiocciput (basal bone of the skull at the back) articulates with the atlas (top joint of the backbone) by means of a single condyle (protuberance). All reptiles, with the exception of the Chelonians (Turtles), and a few others, are furnished with teeth: these are formed chiefly of dentine with a layer of enamel.

Dentition.—

Some teeth have solid crowns (pleodont); some grow from persistent pulps (coelodont); socketed teeth (thecodont) are inserted in alveoli; some are fused with the supporting bone along the outer rim or top (acrodont); whilst others are developed laterally along the flange-like inner rim of the jaw (pleurodont).

Permian and Triassic Reptiles.—

The history of Reptilia commences in Permian and Triassic times, when they were notably represented by the Theromorphs, Pareiasaurus and Tritylodon in South Africa; the Proterosauria of the European and American Permian and Trias, represented by the lizard-like Palaeohatteria and the dorsally frilled Dimetrodon, with its formidable array of neural spines; also the Rhynchosauria, with their beak-like jaws of the same formations. These two groups constitute the order Rhynchocephalia, which is represented at the present day by the Tuatera of New Zealand.

Triassic Reptile, New Zealand.—

The earliest Australian reptilian record is that of a vertebra of Ichthyosaurus from the Kaihiku Series of Mount Potts, New Zealand (Triassic). This specimen was named I. australis by Hector, but since that species name was preoccupied by McCoy in 1867 it is suggested here that the New Zealand species should be distinguished as I. hectori. The New Zealand occurrence of Ichthyosaurus makes the geological history of the genus very ancient in this part of the world.

Jurassic Reptiles.—

At Cape Paterson, Victoria, in the Jurassic coal-bearing sandstone an extremely interesting discovery was made a few years ago, of the ungual bone (claw) of a carnivorous Deinosaur, probably related to Megalosaurus of the European Jurassic and Cretaceous beds (See Fig. 126, 3, 3 A). The presence of an animal like this in Australia points to the former existence of a concomitant terrestrial animal fauna, upon which the deinosaur must have preyed.

Lower Cretaceous Reptiles.—

The Rolling Downs formation (Lower Cretaceous) of the Thompson and Flinders Rivers in Queensland has yielded remains of a Tortoise, Notochelone costata (see antea, Fig. 17); and the interesting Fish-lizard Ichthyosaurus. Numerous and well preserved remains of I. australis McCoy come from the Flinders River (Fig. 133); whilst I. marathonensis is recorded from Marathon Station, Queensland. The former species is typically represented by a nearly complete skeleton, and was considered by McCoy to be one of the largest examples of the genus, since a perfect specimen would probably reach the length of 25 feet. Its teeth resemble those of I. campylodon, Carter, from the English Chalk. Of the Sauropterygia two species of Pliosaurus (P. macrospondylus and P. sutherlandi) have been described from the Lower Cretaceous of the Flinders River; whilst the latter species has also occurred at Pitchery Creek, Central Queensland and at Marathon. P. macrospondylus is distinguished from P. sutherlandi by the roughened edges of the vertebral centra. Another genus of the “lizard-finned” reptiles (Sauropterygia), viz., Cimoliosaurus, occurs in the Upper Cretaceous of White Cliffs, New South Wales (Fig. 134 B, C.)

Cretaceous Reptiles, New Zealand.—

The Waipara Series (Cretaceous) of New Zealand contains a fairly large number of reptilian species belonging to several genera among which may be mentioned Plesiosaurus, Polycotylus, and Cimoliosaurus among the Sauropterygia; and Tylosaurus and Taniwhasaurus (Fig. 134 A), marine lizard-like reptiles, belonging to the sub-order Pythonomopha.

Cainozoic and Pleistocene Reptiles.—

The later Cainozoic deposits of Queensland contain remains of Crocodiles referred to Pallymnarchus pollens (from Maryvale Creek) and Crocodilus porosus (from Chinchilla and Arcola, near Brisbane, Queensland). The former species has also occurred at Clunes, whilst Crocodilus porosus is recorded from the Loddon Valley, both in Victoria. Another late Tertiary reptile is the remarkable Horned Turtle, Miolania oweni, which is found in Queensland in Pleistocene deposits (Fig. 134 D), and in the Pliocene (Deep Leads) of Gulgong, New South Wales; whilst a second species of the same genus, M. platyceps, is found in coral sand at Lord Howe Island, 400 miles distant from Australia. This genus has a skull with large bony protuberances, giving it a horned appearance, and the tail is encased in a bony sheath. A species of Miolania is also described from Patagonia. The Cave deposits of Wellington Valley, New South Wales, as well as the fluviatile deposits of Queensland, have, yielded the bones of several genera of lizards, including the Giant Lizard (Megalania), which, in its length of 20 feet exceeded that of most living crocodiles.

Birds.—

BIRDS (AVES).—These warm-blooded animals are closely related to Reptiles in many essential particulars; and are generally considered to more nearly approach the Deinosaurs than any other group. The Ratitae (“Raft-breasted” or keel-less birds) and Carinatae (with keeled breast-bones), a sub-class including most modern birds, were probably differentiated before the Cainozoic period.

Jurassic Bird.—

The oldest recorded bird, the remarkable Archaeopteryx, of the Upper Jurassic of Bavaria in Europe, belonging to the Saururae (Reptilian-tailed) is, so far, restricted to the beds of that age.

Miocene Bird, New Zealand.—

The earliest known birds in Australasia occur in the Miocene rocks (Oamaru Series), of New Zealand. In this series, in the Marawhenua Greensands, a Giant Penguin, Palaeeudyptes antarcticus is found at Kakanui near Oamaru, at Curiosity Shop near Christchurch and at Brighton near Nelson, New Zealand: this interesting occurrence shows that these restricted antarctic birds had already become an established type as early as the Miocene.

Victorian Cainozoic Bird.—

The impression of a bird’s feather, probably of a Wader, has lately been described from Western Victoria (see antea Fig. 16 and Fig. 135). This occurs in ironstone, on the surface of which are also impressions of Gum (Eucalyptus) and Native Honeysuckle (Banksia) leaves, of species closely related to those now growing in the same locality. This ironstone is probably of Janjukian age, and may therefore be coincident with the New Zealand occurrence of the Palaeeudyptes in the Oamaru Series.

Pliocene Moa, New Zealand.—

In the Wanganui System (Pliocene) the Putiki Beds have yielded bones of a small Moa (Dinornis), probably the oldest example of the group of great flightless birds which later predominated in New Zealand.

Pleistocene Struthious Birds, Australia.—

Bones of a struthious or Ostrich-like bird, described by Owen under the name of Dromornis australis, a bird as large as the Moa, have been recorded from the Pleistocene of Peak Downs and the Paroo River, Queensland. Indeterminate species of the same genera occur in Phillip Co., New South Wales, and the Mount Gambier Caves, South Australia; whilst Dromaeus patricius is known from King’s Creek, Darling Downs, Queensland.

Genyornis newtoni is an extinct bird allied to the Emeus; it has been found in Pleistocene deposits at Lake Callabonna, South Australia, and other fragmentary remains have been identified by Dr. Stirling and Mr. Zietz from Mount Gambier and Queensland. Regarding the build and habits of Genyornis, those authors remark that “Its legs combine a huge femur nearly as massive, in all but length, as that of Dinornis maximus, and a tibia equalling that of Pachyornis elephantopus with the relatively slender metatarse of Dinornis novae-zealandiae (ingens) and toes which are insignificant beside those of any of the larger moas.”... “In height it may be confidently stated to have been from 6 feet to 6 feet 6 inches, that is if the neck should have been of proportions similar to those of Pachyornis elephantopus.” Those authors also attribute a slow, sluggish habit to the bird, and suggest that herbage rather than roots formed its food. It is very probable that the footprints of birds found in the older dune rock of Warrnambool, Victoria, associated with the doubtful “human footprints” may have been made by Genyornis or a related form.

An extinct Emu, Dromaeus minor, has lately been described from the sub-recent deposits in King Island, Bass Strait.

Pleistocene Carinate Birds, Australia.—

Many genera of carinate birds belonging to living Australian types have been identified by De Vis from the fluviatile deposits on the Darling Downs, Queensland. These include Falcons (Taphaetus and Necrastur); a Pelican (Pelicanus); an Ibis (Palaeopelargus); a Spoonbill (Platalea); Ducks (Anas, Dendrocygna, Biziura and Nyroca); a Darter (Plotus); a Pigeon (Lithophaps); a Ground-pigeon (Progura); a Mound-builder (Chosornis); a Rail (Porphyrio); Moor-hens (Gallinula, Tribonyx and Fulica); and a Stork (Xenorhynchus).

Pleistocene and Holocene Birds, New Zealand.—

In New Zealand numerous remains of birds are found, chiefly in the Pleistocene strata, associated with Moa bones: such are Cnemiornis, the Flightless Pigeon Goose (Fig. 135); Harpagornis, a predatory hawk-like bird larger than any existing eagle; and Aptornis, an extinct Rail. The sand-dunes, peat bogs, swamps, river alluvium, caves and rock shelters of New Zealand often contain numerous remains of the gigantic Moa birds included in the genera Dinornis, Pachyornis and Anomalopteryx, of which perhaps the best known are D. giganteus, D. maximus (Fig. 136), D. robustus, P. elephantopus (Fig. 137), and A. antiqua. Some of the species have become so recently extinct that remains of their skin and feathers have been preserved in fissures in the rocks where they were shielded from the influence of air and moisture. The remains of Moa birds are very abundant in some of the localities as at Hamilton in Southland, where, as Hutton estimated, the remains of at least 400 birds were contained within a radius of 25 feet.

Mammalia: Early Types.—

MAMMALIA.—The history of those warm-blooded animals, the mammals, commences in the early part of the Mesozoic period. It was then that the skull began to assume the characters seen in the modern quadrupeds, and their well-formed limb-bones, and fusion of the three bones on each side of the pelvic arch to form the innominate bone, also show relationship to the later types. The earliest ancestral mammalian forms seem to be related to the theromorphic reptiles, predominant in the Permian and Trias. The mammals first to make their appearance were probably related to those of the Monotreme and Marsupial orders. More nearly related to the former is the group of mammals of the Mesozoic period, the Multituberculata.

Multituberculata.—

This group comprises the Triassic Tritylodon (South Africa and Germany); the Upper Jurassic Bolodon (England and United States); the Upper Jurassic to Lower Cainozoic Plagiaulax (England, United States and France); and the Lower Eocene Polymastodon (New Mexico). The molar teeth are ridged longitudinally, and carry numerous tubercles, hence the name of the group, and resemble the deciduous teeth of the Duck-billed Platypus (Ornithorhynchus).

Monotremata.—

The Monotremata are represented at the present day in Australia and New Guinea by the Echidna or Spiny Anteater, and by the Ornithorhynchus or Duck-billed Platypus of Eastern Australia and Tasmania. These egg-laying mammals show relationship towards the reptiles both in structure and in methods of reproduction.

A Pliocene species of Ornithorhynchus (O. maximus) has been recorded from the Deep-leads of Gulgong, New South Wales, and the same beds have yielded the remains of Echidna (Proechidna) robusta. Remains of another species, Echidna, (P.) oweni, have been described from the Pleistocene Cave-breccias of the Wellington Valley Caves, New South Wales; and Ornithorhynchus agilis is found in deposits of similar age in Queensland.

Marsupials.—

The Marsupials or pouched mammals belong to the sub-class Metatheria. They are divided into Diprotodontia and Polyprotodontia, accordingly as they possess a single pair of incisor teeth in the lower jaw, or many front teeth, hence the names of the two sub-orders. A later classification of the Marsupials is that of their division into syndactyla and diadactyla.

The diadactyla have the second and third toes separate, and are represented by the family Dasyuridae or Native Cats. These are polyprotodont. They are the most archaic of the marsupial group. Remains of Dasyurus, both of extinct and still living species are found in Pleistocene Cave-breccias in Victoria and New South Wales. The Tasmanian Devil (Sarcophilus ursinus) (Fig. 138, 139) and the Tasmanian Wolf (Thylacinus cynocephalus), still living in Tasmania, have left numerous remains on the mainland, in Victoria and New South Wales. Of the latter genus an extinct species is T. major from the Pleistocene of Queensland (Fig. 140).

The syndactyla have the second and third toes enclosed in a common skin. The Peramelidae and the Notoryctidae are polyprotodont. The remainder are all diprotodont. The Peramelidae or Bandicoot family are represented in Pleistocene Cave-breccias in New South Wales by the genera Peragale and Perameles.

Pleistocene Diprotodonts.—

Pleistocene remains of the diprotodont forms of this syndactylous group are Phascolomys (the Wombat), perhaps ranging as low as Upper Pliocene (P. pliocenus) (Fig. 141); Phascolonus (P. gigas) (Fig. 142 A)[4], a large Wombat from Queensland and New South Wales and South Australia; the Giant Kangaroos, as Macropus titan (Queensland, New South Wales, Victoria and South Australia), Procoptodon goliah (Queensland, New South Wales and Victoria), Sthenurus atlas (New South Wales, Queensland, Victoria and South Australia), Palorchestes azael (Victoria, New South Wales and Queensland); also the great Diprotodon, the largest known marsupial, as large as, and rather taller than, a rhinoceros, found in almost every part of Australia, with an allied form referred to Nototherium occurring also in Tasmania (Figs. 143, 144, 145). Nototherium (Queensland, South Australia and Victoria), was a smaller animal than Diprotodon, with a shorter and broader skull and similar dentition. Remains of the extinct “Marsupial Lion,” Thylacoleo carnifex, an animal allied to the phalangers, have been found in Cave-deposits in New South Wales, Queensland, Victoria and Western Australia. Incised bones of other animals, which are believed to have been gnawed by Thylacoleo, have been found associated with its remains. Thylacoleo possessed a peculiar dentition, the first pair of incisors in the upper jaw being very large and trenchant, whilst the canine and two anterior premolars are small and functionless: the lower jaw has also a pair of large first incisors, behind which are two small premolars, and an enormous chisel-edged last premolar biting against a similar tooth in the upper jaw (Fig. 146).

Oldest Known Marsupial.

The oldest marsupial found in Australia is probably Wynyardia bassiana (Fig. 147), whose remains occurred in the Turritella-bed at Table Cape, which is either of Miocene or Lower Pliocene age. This stratum occurs above the well-known Crassatellites-bed (Miocene) of that locality. So far as can be gathered from its incomplete dentition, Wynyardia represents an annectant form between the Diprotodonts and the Polyprotodonts.

Pleistocene Genera, also Living.—

Besides the genera above enumerated, many other marsupials of well-known living species are represented by fossil remains in Cave-deposits and on “sand-blows” in most of the Australian States. The genera thus represented in the Pleistocene deposits of Australia are Bettongia (Prehensile Rat-Kangaroo); Dasyurus (Native Cat); Hypsiprymnus (Rat-Kangaroo); Macropus (Kangaroo); Perameles (Bandicoot); Petaurus (Flying Phalanger); Phalanger (Cuscus); Phascolomys (Wombat); Sarcophilus (Tasmanian Devil); Thylacinus (Tasmanian Wolf).

Cetacea.—

The order Cetacea includes Whales, Dolphins and Porpoises. The earliest known forms belong to the sub-order Archaeoceti, and whilst absent from Australian deposits, are found in the Eocene of Europe, Northern Africa and North America.

Odontoceti: Toothed Whales.—

Remains of Cetacea are first met with in Australian rocks in the Oligocene (Balcombian) of Victoria. At Muddy Creek near Hamilton fragments of ribs and other bones of cetacea, not yet determined, occur in the tenacious blue clays of the lower part of the Clifton Bank section. In Australia and New Zealand the oldest determinable remains of this order belong to the Odontoceti, members of which range from Miocene to Pliocene. Teeth of the toothed whales like Squalodon of the Miocene of France and Bavaria have been found in New Zealand (Kekenodon); in South Australia (Metasqualodon); and in Victoria (Parasqualodon). In Victoria the teeth of Squalodontidae occur in the Janjukian beds of Cape Otway, Waurn Ponds and Torquay, represented by molars and anterior teeth of Parasqualodon wilkinsoni (Fig. 142 B, C). The same species also occurs at Table Cape, Tasmania, in beds of similar age. Teeth of Metasqualodon harwoodi (Fig. 142 D) occasionally occur in the white polyzoal rock of the Mount Gambier district, South Australia. The gigantic toothed whale, Kekenodon onamata (Fig. 142 E) occurs in the Marawhenua Greensands (Oamaru Series) at Waitaki Valley, Waihao, Ngapara, Waikouaiti and Milburn in New Zealand. The molar teeth of this striking species, with their serrated crowns, measure nearly five inches in length.

Ear-bones of Whales.—

The tympanic bones of whales are not uncommon in the Janjukian beds of Waurn Ponds, near Geelong, Victoria; and they are occasionally found in the basement bed of the Kalimnan at Beaumaris, Port Phillip. In the absence of any distinctive generic characters they have been referred to the quasi-genus Cetotolithes (Fig. 142 F). McCoy has expressed the opinion that they may perhaps be referable to the ziphioid or beaked whales, for undoubted remains of that group, as teeth of Ziphius geelongensis, occur in these same beds; as well as portions of their rostrate crania, in the Kalimnan basement beds at Grange Burn, near Hamilton. The large curved and flattened teeth of Ziphius (Dolichodon) geelongensis are occasionally found, more or less fragmentary, in the polyzoal rock of Waurn Ponds.

Kalimnan-Scaldicetus.—

From the Kalimnan Series (Lower Pliocene) of Beaumaris, Port Phillip, there was described a short time since, a remarkably well preserved specimen of Scaldicetus tooth belonging to a new form, S. macgeei (Fig. 148). Another species of the genus, with teeth of a slender form, has been found in the same geological series, at Grange Burn, near Hamilton. In only one other locality besides Australia does the genus occur, viz., at Antwerp, Belgium, in Crag deposits of Lower Pliocene age.

Sirenia.—

The order Sirenia (Manatees and Dugongs) is represented in the Australian Pleistocene by ChronozoÖn australe. The remains consist of the parietal and upper part of the occipital bones of the skull, and were discovered in the fluviatile deposits on the Darling Downs, Queensland. This fossil skull, according to De Vis, had a shallower temporal fossa and feebler masticating muscles, as well as a less highly developed brain than the existing Dugong.

Carnivora.—

The order Carnivora is represented in Australia by the Native Dog or Dingo (Canis dingo). It is by no means a settled question whether the Dingo can boast of very great antiquity. The evidence of its remains having been found under volcanic tuff beds in Victoria is not very convincing, for the original record does not indicate the precise position where the bones were found. The fact of the remains of the Dingo having been found in Cave deposits often associated with extinct marsupials, goes a good way to prove its antiquity. McCoy was strongly inclined to the view of its Pleistocene age, and points out that it shows cranial characters intermediate between the Dogs of South America and the Old World. Fossil remains of the Dingo, associated with Pleistocene mammalian forms have been recorded from the Wellington, Valley Caves, New South Wales; from the Mount Macedon Cave, near Gisborne; and in the neighbourhood of Warrnambool, Western Victoria.

Pinnipedia.—

Of the fin-footed Carnivores or Seals and Walruses, the earliest Australasian record is that of the remains of a small seal in the Okehu shell-beds near Wanganui, found in association with the bones of a small Moa-bird (Dinornis).

Newer Pliocene Seal.—

This seal was referred by Hector to Arctocephalus cinereus, a species synonymous, however, with the widely distributed living Seal, Otaria forsteri, Lesson, of the Southern Ocean. Another and larger species of eared seal allied to the living Fur Seal, Otaria forsteri, occurs in Victoria.

Pleistocene Seal.—

This fossil was named Arctocephalus williamsi by McCoy, and was found in Pleistocene deposits at Queenscliff, Port Phillip, at 5 feet below the surface, in marl and sand stone overlain with limestone. Although referred at the time of description to the Pliocene, it has since been proved that at this locality there is a considerable thickness of practically sub-recent material which is more accurately classed with the Pleistocene. Similar remains of eared seals are not uncommon in the Pleistocene deposits of the Otway Coast.

Subrecent Human Remains.

On turning to the occurrence of “human fossils” in Australia we find the geological evidence for any great antiquity of man on this continent to be very scanty and inconclusive. This does not, however, imply that man’s existence in Australia will not eventually be proved to date back far beyond the period of the “kitchen middens” of modern aspect, such as are now exposed on the slopes behind the sea-beaches, and on the inland camping grounds. Almost all the records of Australian human remains that have been found in other than ordinary burial places, have proved to be of comparatively recent date. For example, the partially lime-encrusted body found in the cave in the Mosquito Plains, north of Penola, South Australia, recorded by Tenison Woods, is that of an aborigine who, in the early days of settlement, crawled into the cave in a wounded condition. Other occurrences of human remains in caves, but of fairly recent date are, a child’s skull found in a small cave at Bungonia, Co. Argyle, New South Wales, recorded by Etheridge; and the non-petrified limb-bones found in a cave at Wellington, New South Wales, recorded by Krefft, which were probably washed in from the surface in recent times. As regards the former, in Western Australia, as observed by Froggatt, the natives at the present time seek shelter in caves, where these occur, instead of building mia-mias.

A more interesting, because probably much older, occurrence of human remains has been described by Etheridge and Trickett from one of the Jenolan Caves (Skeleton Cave); and those authors conclude from "The great lapse of time that must have accrued to enable the changes already outlined to have taken place since the introduction of the remains into the Skeleton Cave," that these remains are ancient.

Curious footprints supposed to resemble impressions of human feet with accompanying impress as if made by natives seated, have been long known from the older sand-dune rock of Warrnambool. They were found at Kellas’ Quarry, on the Port Fairy Road in 1890 and at a depth of 54 feet. In November, 1912, a further discovery of similar footprints were found at Messrs. Steere Bros.' Quarry, Warrnambool, at a depth of 10 feet, as a block of stone was being removed for building purposes. These footprints are even more obscure than those previously found, and it would be unsafe to affirm their human origin, although they are suggestive of such. Their antiquity is certainly great, since the lavas and tuffs of the Tower Hill district are found overlying this old dune-rock. Other footprints associated with these resemble those of the Dingo and a gigantic bird, possibly like Genyornis.

Probable Origin of Aborigines.—

Ethnology appears to throw more light upon the subject than does geology. Australia has in the past been peopled by two distinct types of man. (1), the ancestors of the Tasmanians, now alas, extinct, who according to some authorities came by way of Australia from Papua through the Malay Peninsula, passing over to Tasmania from the mainland before the separation caused by the subsidence of the Bass Strait area; and who were represented by a negroid or woolly-haired type: (2), the present aboriginals of Australia, showing affinities with the Dravidians of Southern India, a primitive race from whose original stock the white Caucasian races of Europe were derived. By intermarriage with a negroid race like the Melanesian, it is supposed that the black Caucasian gave rise to the present Australian mixed aboriginal type, with negroid features, but possessing the long black hair and keener intellect of the “melanochroi,” as the dark Eurasian stock was termed by Huxley.

Aboriginal Implements.—

The stone implements fashioned by the Tasmanian aboriginals were roughly chipped and of primitive type, of such forms as used at the present day by the Bushmen of South Africa, and representing the eoliths and palaeoliths of early man in the south of England. The implements of the Australian aboriginals on the other hand include besides these both flakes and worked and polished tools, such as were produced by the Neolithic men of Europe, as contrasted with the typically rough palaeolithic tools of the Tasmanian, who never grooved his axes for hafting as did the Australian aboriginal. According to some authorities the Tasmanians represent palaeolithic or even eolithic man in the character of their implements; whilst the Australian resembles the Middle or Mousterian stage of early man in certain of their ethnological characters and in the forms of their implements, although a marked exception is seen in their manufacture of polished adzes, of the neolithic period and in the use of bone implements such as were used in Europe in Upper Palaeolithic times. So far no human remains or handiwork in the form of chipped implements have been found in other than superficial deposits, either in Tasmania or Australia. The incised bone-fragment found near Ballarat, in a bed of silt beneath a sheet of basalt which flowed from Mount Buninyong, is believed by some to be evidence of man’s handiwork in the early Pleistocene, though by others thought to have been cut by the teeth of the “marsupial lion” (Thylacoleo). A stone axe of basalt, grooved for the purpose of mounting in a handle, was found in gravel at Ballarat at a depth of 22 inches from the surface. This, however, is no proof of man’s antiquity, for superficial deposits of much greater depth are easily accumulated within a short period. Another implement was found at Maryborough in Queensland in gravels at a depth of 4 feet from the surface, but not below the basalt of the main lead. In this case it is believed that the implement may have fallen into a natural hollow or wombat-burrow. A bone pointer, such as used by native medicine men, was some years ago found buried in the Miocene marls of Waurn Ponds near Geelong. Its presence in so old a rock is easily explained from the fact that in the aboriginal ceremonies the pointer was buried after the incantations. Seeing the difficulties in the way of discovering reliable occurrences of man’s handiwork in isolated examples amongst the older superficial deposits of silt and gravels, the ancient sand-dunes of Victoria, which date back at least to Upper Pliocene, should afford favourable conditions for the preservation of any really ancient kitchen middens, did such exist. Moreover, these deposits would have been less liable to disturbance when once they were covered, than the inland deposits, for the former are now consolidated into a tolerably hard stone.

Antiquity of Man in Australia.—

A strong argument in favour of a considerable antiquity for man in Australia is the fact that the dialects are many, and marriage and tribal customs more complex and intricate than would be found in a comparatively recent primitive race. In any case, it is quite possible, if not probable, that man was in southern Australia before the termination of the last phase of volcanic activity, since the tuff beds of Koroit, for example, are quite modern and were laid down on a modern sea-beach strewn with shells identical in species and condition with those now found thrown up in the vicinity at high tide. This view is quite compatible with the occurrence of dingo remains (assuming this animal was introduced by man) in cave deposits in Australia, associated with extinct forms of marsupials.
