The Fossil Hybodus Shark Fin Spine from Morocco is from the Cretaceous period, offering a fascinating glimpse into the ancient world of sharks. Hybodus was a genus of sharks that existed from the Late Permian to the Early Cretaceous, with distinctive features including a streamlined body, sharp teeth, and prominent dorsal fin spines.

The fin spine, preserved in fossil form, served as a crucial structure for stabilizing and maneuvering the shark as it navigated through ancient seas. These spines were composed of dense cartilage, providing strength and flexibility while also acting as a defensive mechanism against predators.
