Coming at you is the hybodus, or “hump tooth!” It’s one of a few species in the Hybodontidae family and lived about 180 million years ago. Hybodontids were common sharks during most of the Mesozoic and are regarded as a sister group to modern sharks and rays. They had robust braincases, heavy dorsal spines, and well-developed rib cages (an unusual feature in sharks). The model pictured shows what Hybodus may have looked like. See it up close in the Hall of Vertebrate Origins on the Museum’s fourth floor.
