Dinosaurs are ancient reptiles that are extinct in the real world. Dinosaurs and the related pterosaurs, have appeared in the various continuities of the Sonic the Hedgehog series in some form at least once.
In Sonic and the Secret Rings, dinosaurs appear in abundance in Dinosaur Jungle, the second World. All of the dinosaur species featured in the stage include Triceratops, Parasaurolophus, Tyrannosaurus rex, Pteranodon, Stegosaurus, Apatosaurus and Allosaurus.
Additionally in Sonic Rush Adventure, one of the many decorations Sonic and Blaze can get for Southern Island is an Apatosaurus. Ghost Rex, while not technically a dinosaur, is one of the bosses of the game.
