is a dorsal spine of the extinct Cretaceous aged shark Hybodus. These spines helped to support the dorsal fins of the shark.

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.
