“A chicken grows up in a little less time than an ostrich. An ostrich takes a whole year. A chicken takes a few months.”

“A dinosaur out of context is like a character without a story. Worse than that, the character suffers from amnesia.”

“A lot of Montanans are teed off that local finds usually end up in New York.”

“Almost all of my graduate students say that they got interested in dinosaurs because of 'Jurassic Park.'”

“Children have a great urge to learn about dinosaurs.”

“Dinosaurs are built just like birds - they can squat down, they can get up. Mammals, when we lay down, we throw our legs out to the sides - birds cannot do that. Dinosaurs could not do that either.”

“Dinosaurs replace their teeth throughout their life. And T. rex replaced all of their teeth every year.”

“Evolution - evolutionary change - does not happen quickly.”

“I encourage people who don't believe in evolution to look for horses in Jurassic Solenhofen limestone.”

“I found my first dinosaur bone when I was 6, growing up in Montana. Ever since then I've been interested in dinosaurs.”

“I just cannot imagine why anyone would want to be really famous. You go to a restaurant and people are pointing at you and they talk about you and they whisper and it is very disconcerting; it is a very odd feeling.”

“I think most of the dinosaur specimens we find represent subadult sizes.”

“I'm trying to figure out the biology of dinosaurs and what they were like as living creatures.”

“'Jurassic Park' has a lot of science in it - and a lot of it is wrong - but if it was all accurate, it would be a documentary.”

“Keratin can be very colorful, as we see in birds. We'd expect dinosaurs to be very colorful because they basically invented the characteristics we see in birds.”

“Life histories tell you just about everything you need to know about an animal.”

“Most people looking for dinosaurs are looking for beautiful skeletons.”

“My father had owned a ranch when he was younger, in Montana, and he remembered riding his horse across the prairie and seeing some large bones sticking out of the ground. He was enough of a geologist, being a sand and gravel man, to have a pretty good notion that they were dinosaur bones.”

“Right now people are interested in genetic engineering to help the human race. That's a noble cause, and that's where we should be heading. But once we get past that - once we understand what genetic diseases we can deal with - when we start thinking about the future, there's an opportunity to create some new life-forms.”

“Scientists who play by someone else's rules don't have much chance of making discoveries.”

“T Rex could not run.”

“The fossil record is incredible when it preserves things, but it's not a complete record.”

“There's an incomparable rush that comes from finding dinosaur bones. You know you're the first person to lay hands on a critter that lived 80 or 90 million years ago.”

“Triceratops is very common: they are the cows of the Cretaceous; they are everywhere.”

“Unfortunately, with dinosaurs, we haven't had enough specimens to determine how much variation there is within a species.”

“We all have genes that come from our ancestors that aren't used - they're not turned on. So we actually carry ancient genes with us. If you could figure out how to turn those on, you could resurrect ancient characteristics from our ancestors.”
