Elopopsis (meaning "Elops-like face") is an extinct genus of marine ray-finned fish that lived during the Late Cretaceous ( Cenomanian to Turonian) of Europe, North Africa and North America. It was a member of the Crossognathiformes, in the family Pachyrhizodontidae.
It contains the following species:
Indeterminate remains referable to Elopopsis are known from the Cenomanian of Saskatchewan, Canada (Ashville Formation) and the United States (Greenhorn Limestone of Colorado, Graneros Shale of Nebraska), indicating that they inhabited the Western Interior Seaway early on. The former species "E." dentex from the Komen Limestone appears to be a specimen of Enchodus.
It was likely a predatory fish that fed on smaller fish. A well-preserved specimen of E. microdon from the Hesseltal Formation of Germany has fossilized intestinal casts.
