[1] However, due to a high degree of convergent evolution in the relationship-determining traits among many mosasaurs (especially among prognathodontines), phylogenetic results between each study are seldom consistent, mystifying exactly which species must be revised to stabilize the Prognathodontini. University of Bath. Fossils from the same beds show damage from acids, with teeth and bone eaten away.

The dorsal (back) vertebrae are slightly longer than wide with tall neural arches, rounded articular surfaces, and large rectangular transverse processes. They are procoelous, meaning that the front side is deeply cupped concavely and the back side is bulged convexly. It had a short, wide muzzle and massive, conical teeth like those of an orca which let it seize and rip apart huge prey.
