Casieroides
''Casieroides'' is an extinct genus of prehistoric freshwater Actinopterygii, ray-finned fish. It contains a single species, ''C. yamangaensis'' from the Early Cretaceous Loia Formation of the Democratic Republic of the Congo. Its taxonomic identity is uncertain, as it has alternatively been classified as a "Clupeoidei, clupeoid", a Pattersonellidae, pattersonellid, or a Salmonidae, salmoniform. The latter classification is now thought to be a Wastebasket taxon, wastebasket treatment.

Clupavus
''Clupavus'' is an extinct genus of marine ray-finned fish that lived during the middle of the Cretaceous period. It is known from North Africa, Europe, Brazil, and possibly North America. Taxonomy It contains the following species: * ''C. brasiliensis'' - Aptian of Bahia, Brazil (Marizal Formation) * ''C. maroccanus'' - Cenomanian of Morocco (Jbel Tselfat), late Cenomanian/early Turonian of Germany (Hesseltal Formation) Fossils of an indeterminate ''Clupavus'' species are abundant in the Albian-aged Pietraroja Plattenkalk of Italy, and the Cenomanian-aged Komen Limestone of Slovenia. A few specimens of a potential indeterminate species are also known from the Albian-aged Mowry Shale of Wyoming, USA. The genus was initially described in 1950 with the species ''C. neocomiensis'' (Bassani, 1879) as its type species, based on a specimen from Morocco classified ''C.'' cf. ''neocomiensis''. In 1968, the original ''C. neocomiensis'' was found to be synonymous with ''Leptolepis b ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
