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.
