Dinosaurs are a diverse group of animals that were the dominant terrestrial vertebrates for over 160 million years, from the late Triassic period until the end of the Cretaceous. Also; you will find a lot of random extinct reptiles being posted here that aren't technically "dinosaurs" (not included in the superorder), but are from the Mesozoic era.
