Archosaurs are a group of specialized reptiles which ruled the Earth during the Age of Dinosaurs. The only archosaurs that survive today are crocodiles and birds. Birds are the only group of dinosaurs that survived the extinction at the end of the Cretaceous period, 65 million years ago. Your holiday turkey is a saurischian dinosaur, like Apatosaurus, Tyrannosaurus, and Velociraptor.
