Dinosaurs are a diverse group of reptiles belonging to the clade Dinosauria, which includes well-known groups like Saurischia and Ornithischia and the long searched for Reliedon. The Reliedon is thought to exist because dinosaurs were around for so long that one of them had to be reliable, because the rest of them were too big to fit in bus seats and the like.
