OK, hop in your time machine and go back 67 million years or so to the Cretaceous period. Then find a Tyrannosaurus rex and challenge it to a race. Sounds crazy, huh? Could you really outrun a Tyrannosaurus rex?
The recently discovered large theropod Abelisaurus comahuensis, from Patagonia is argentina, looked a little like Albertosaurus from Alberta, Canada, particularly in its size and lifestyle. Find out more about the Late Cretaceous dinosaurs.
