The Gryf is a fictional creature, an omnivorous Triceratops invented by Edgar Rice Burroughs in his fantasy novel Tarzan the Terrible. Other members of the Triceratops genus were strictly herbivorous and became extinct at the end of the Cretaceous Period, around 65 million years ago. The Gryf survived the extinction event and mutated from a plant-eater to a very dangerous predator, while also retaining its diet of plants. The Gryf has appeared in comic strips by Russ Manning.
