From Wikipedia, the free encyclopedia
Non-avian Dinosaurs are a group of reptiles that dominated terrestrial ecosystems for over 160 million years, from around 230 million years ago until 66 million years ago, at the end of the Cretaceous period,[1] when all non-avian dinosaurs became extinct. Their remains have been found on every continent. Birds are avian dinosaurs.
