Dinosaur Discoveries

Dinosaur Boom Linked to Rise of Rocky Mountains

About 75 million years ago, duck-billed and horned dinosaurs flourished in Canada, while only a few of these species emerged in the United States.

Scientists believe that this diversity among dinosaurs caused a dinosaur boom when the Rocky Mountains were formed, creating geographic and ecological barriers between species. This not only rapidly increased the population of certain dinosaur species, but it in turn reduced the pace at which new species evolved.
