About 145 million to 200 million years ago during the Jurassic Period, Earth’s creatures had to contend with one of the most powerful, ferocious predators that ever lived—a clawed, flesh-eating, sharp-toothed behemoth of a dinosaur that stalked the floodplains of what would become Western North America.
Despite what Hollywood might have you think, we’re not talking about Tyrannosaurus rex, which wouldn’t appear until the Cretaceous, the period immediately following the Jurassic. But as researchers reported last week in the journal PeerJ, a newly-described species called Allosaurus jimmadseni, which lived some 70 million years before its more famous carnivorous cousin, certainly made for a worthy opening act. A. jimmadseni roamed the North American continent between 152 million years ago and 157 million years ago, making it the oldest species of Allosaurus discovered so far, reports George Dvorsky for Gizmodo.

Pangea appears to be correct. I had to look that up.
Wasn’t there just one super land mass at that time? Not sure what it was called?
Edward, Pangea?
