5.6" Fossil Shark (Hybodus) Dorsal Spine - Morocco

This is an 5.6" fossil, dorsal spine of a shark (Hybodus) from the Kem Kem Basin, Taouz, Morocco. This specimen has one repaired crack at the point.

Hybodus was a small shark that grew up to 2 meters in length and was likely an opportunistic predator. It had a streamlined shape ideal for hunting down fast prey and two different types of teeth: sharp cutting teeth for catching prey and flatter grinding teeth for crushing. This combination may have been the key to Hybodus' success.
