Pluridens is a genus of halisaurine mosasaur that lived in shallows seas in West Africa during the late Campanian-Maastrichtian.


Two species of Pluridens are known, P. walkeri and P. calabaria.[1][2] P. walkeri is known from the Maastrichtian of southwest Niger, whereas P. calabaria is found in slightly older (late Campanian) deposits in Nigeria.

Pluridens was synonymized with Halisaurus by Lindgren and Siverson (2005),[3] but subsequent studies rejected the synonymy.[4][5]
