From Wikipedia, the free encyclopedia
Diapsids ("two arches") are a group of amniote tetrapods that developed two holes (temporal fenestra) in each side of their skulls about 300 million years ago during the late Carboniferous period.[1] The diapsids are extremely diverse, and include all crocodiles, lizards, snakes, turtles, tuatara, birds and non-avian dinosaurs. Although some diapsids have lost either one hole (lizards), or both holes (snakes), or have a heavily restructured skull (modern birds), they are still classified as diapsids based on their ancestry. At least 7,925 species of diapsid reptiles[2] exist in environments around the world today (nearly 18,000 when birds are included).
