Caprina

Caprina is a genus of rudists, a group of marine heterodont bivalves belonging to the family Caprinidae.

These stationary intermediate-level epifaunal suspension feeders lived in the Cretaceous period, from 140.2 to 70.6 Ma. The rudists became extinct at the end of the Cretaceous, apparently as a result of the Cretaceous–Paleogene extinction event.

Fossils of this genus have been found in the sediments of Europe, Japan, Cuba, Mexico and the United States.
