Hybodus Photo from New Dinosaurs Kingdom: Animalia Class: Choridricthyes Conservation Status: Extinct (EX) Found: Worldwide Era: Permian - Cretaceous Lived: 303.4 million - 66 million years ago Diet: Everything. Weight: 90.7kg (200lbs) Size: 2m (6.6ft) Habitat: Shallow seas The Hybodus is an ancient shark species which lived up until 66 million years ago.
