Birdsevolved within theropod dinosaurs during the Jurassic period. Some survived the Cretaceous–Paleogene extinction event, including the ancestors of all modern birds, and birds are the only dinosaurs which survived to the present day.[1][2] The outline of birds covers these avian dinosaurs.
Dinosaur renaissance – a period of renewed interest in dinosaurs, and a shift in the scientific consensus about them.
Prehistoric reptiles – broad category that is intended to help distinguish the dinosaurs from other prehistoric reptiles. Dinosaurs, because of their long and successful reign for many millions of years, are almost exclusively dealt with in their own category of prehistoric life. Therefore, this category covers all the non-dinosaurian reptiles which are often erroneously considered to be dinosaurs, such as the seafaring varieties of plesiosaurs and the flying pterosaurs.
