Dinosaurs are prehistoric reptilian creatures of the Psymonster World that roamed the Earth until their extinction. They first appeared during the Triassic period, 231.4 million years ago, and were the dominant terrestrial vertebrates for 135 million years, from the end of the Triassic until the end of the Cretaceous Period, when the Cretaceous–Paleogene extinction event led to the extinction of most dinosaur groups at the close of the Mesozoic Era. The fossil record indicates that birds evolved from theropod dinosaurs during the Jurassic Period and they are consequently considered to be modern dinosaurs. Some birds survived the extinction event that occurred 65 million years ago, and their descendants continue the dinosaur lineage to the present day.
