In Depth

       Dracopristis is a genus of ctenacanthiforme fish that lived in North America during the Carboniferous period.‭ ‬The‭ ‬ctenacanthiforme fish are generally considered to be like sharks but are also separate from‭ ‘‬true sharks‭’ ‬the kind that we can see swimming around today.‭ ‬Dracopristis like other ctenacanthiforme fish had two large spines rising from its back and supporting two dorsal fins.‭ ‬These spines may have been for defence from other predators.

       Also like other ctenacanthiforme fish,‭ ‬Dracopristis had a large mouth but one not as movable as a modern shark.‭ ‬The teeth of Dracopristis where multicusped so that a hunting Dracopristis could seize and hold on to prey animals more easily.Further reading
