TEDxVancouver - Jack Horner - The Shape-Shifting Skulls of Dinosaurs

"The Shape-Shifting Skulls of Dinosaurs" will focus on our latest discoveries concerning how dinosaur skulls changed as they grew to adult hood, and why it is that some dinosaur species are actually juvenile growth stages of other species. I will illustrate how it is that scientists got it wrong to begin with, and how we figured it all out. The talk will concern field work, studies in morphology, and osteohistology (the microscopic study of bone)

Jack has published more than 170 professional papers, 9 popular books, and more than 100 popular articles. His book Digging Dinosaurs was described by New Scientist Magazine as one of the 250 most important science books of the 20th Century. Jack also directs the largest dinosaur field research program in the world. He was the technical advisor for Steven Spielberg on all of the Jurassic Park movies, and has worked with National Geographic, and The Discovery Channel on numerous dinosaur specials.
Jack is the Curator of Paleontology at the Museum of the Rockies, and Regent's Professor of Paleontology at Montana State University in Bozeman, Montana. He is also a Senior Research Fellow in the Department of Paleobiology at the Smithsonian Institution, and an Honorary Research Fellow with the Natural History Museum in London.

[Elyphaleth Carmona]

*Apatosaurus not Albertosaurus

[Michael Mackprang]

This reminds me of when I was little. When I looked at the restorations, I thought, "Oh look! A Tyrannosaurus!" And then I would read the plaque, Tarbosaurus. I could never keep the number of teeth and shape of the skulls straight. Good thing to know now that I wasn't too far off :)

[David Kelly]

Actually Brontosaurus was Albertosaurus with a Brachiosaurus skull put on to make it look different... Scientists like to name stuff. lol

[HerrBaton]

7th vancouver talk I watch. Nobody really interesting spoke there. I'm suspecting all the inteligentia is extinct in that city.

[laserfan17 .]

he is Smart one of the smartest palaeontologists in the world, but come on, T.rex is a proven predator, and his theories about predatory dinosaurs are pathethic.

still, i am now convinced that he was far smarter than i though. I was in a mistake :/

[conan1174]

Jack Horner, Bob Bakker, Phil Currie, and Gregory S. Paul where some of heroes of Paleontology when I was growing up. 20= Years later I'm still fascinated by dinosaurs and scientists, like Horner, are to me anyway, still the best.

[elementx9]

That wasn't really disproving, you didn't provide any evidence to back this up... You just sort of contradicted him. Anyone can say "Torosaurus is certainly not Triceratops." Proof please.

ATTENTION!:

The ignorant comments on here from people who don't know their butts from their elbows make me laugh. Go to a university, get a good education in paleontology first, and then get years and years of experience in the field.....and then and only then do you have the right to challenge this brilliant man's views on the matter!
