Non-avian Dinosaurs are a group of reptiles that dominated terrestrial ecosystems for over 160 million years, from around until, at the end of the Cretaceous period, when all non-avian dinosaurs became extinct. Their remains have been found on every continent, including Antarctica. Vertebrate paleontology, and well-preserved feathered dinosaurs, have further proven that birds are avian dinosaurs.
