Elopopsis
Elopopsis is an extinct genus of marine ray-finned fish that lived during the Late Cretaceous of Europe, North Africa and North America. It was a member of the Crossognathiformes, in the family Pachyrhizodontidae.
It contains the following species:'
E. crassus - early-mid Cenomanian to middle Turonian of England †E. heckeli August Emanuel [von Reuss|Reuss], 1857 - Cenomanian of the Czech Republic †E. fenzli Heckel, 1856 - late Cenomanian of Slovenia †E. microdon Heckel, 1856 - late Cenomanian of Slovenia, Morocco, and Germany †E. smithwoodwardi Bayer, 1905 - Turonian of the Czech Republic †E. ziegleri' von der Marck, 1868 - late Turonian of GermanyIndeterminate remains referable to Elopopsis are known from the Cenomanian of Saskatchewan, Canada and the United States, 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.
