Hi, my name's Mark Loewen.
I'm a paleontologist at the University of Utah and the Natural History Museum of Utah.
I love watching movies, I love dinosaurs.
I especially love dinosaur movies.
"Jurassic Park," 1993.
So the question is, did dinosaurs make sounds?
Of course, they did.
Are the sounds in "Jurassic Park realistic?
Mm, sure.
Animals like T-rex had huge resonating chambers.
