Dinosaurs

Dinosaurs are ancient reptiles that have been extinct in the real world for millions of years. Dinosaurs, and the related pterosaurs, have appeared in the various continuities of the Sonic franchise in some form at least once.

Games


Dinosaurs appear in abundance in Dinosaur Jungle, the second zone of Sonic and the Secret Rings. The dinosaur species featured include Triceratops, Tyrannosaurus rex, and Apatosaurus.

Archie Comics
Dinosaur-like creatures known as Mobosaurs were the first Mobian species to evolve after the Xorda's destructive attack on the planet. The Mobosaurs were wiped out during the Coming of the Chaos Emeralds, with only four surviving: Mammoth Mogul and the Ancient Walkers.

SatAM


A race of quadrupedal dinosaur-like creatures known as Terapods appear in the SatAM episode "Sonic Past Cool".

Sonic the Comic
Sonic the Comic features the largest appearance of dinosaurs in the Sonic series so far.

The most often seen dinosaur species were the fictional Kohenyu, who were unintentionally hunted to extinction by the Ancient Echidnas. The remains of the Kohenyu reside in the Kohenyu Graveyard, where the Spirit of the Herd is kept "alive" by the Soul Crystal.

Doctor Robotnik also modeled the designs of the Badniks Mekanik and Rexon after the dinosaurs. Additionally, the inhabitants of the Great Mobian Prairie raised a herd of pterodactyls.

Most notably, during a series of time-and-dimensional travels with the Ring of Eternity, Amy Rose and Tekno the Canary discovered that life on several worlds, Mobius included, was created by a race of dinosaurs in spacesuits.
