''Cyclopoma'' (from , 'circular' and 'cover') is an extinct genus of marine Perciformes, perciform fish from the Eocene. It is known from the Ypresian to the Lutetian of Europe and eastern North America. It is alternatively classified in either the Temperate perch, Percichthyidae (which otherwise contains only species from South America and Australia) or in the Centropomidae (represented by modern snooks). The following species are known: * †''C. folmeri'' Weems, 1999 - Ypresian of Virginia, USA (Nanjemoy Formation) * †''C. gigas'' Louis Agassiz, Agassiz, 1833 - Ypresian of Monte Bolca, Italy (=''Amia (fish), Amia indica'' Giovanni Serafino Volta, Volta, 1796, ''Dapalis, Smerdis micracanthus'' Agassiz, 1833) * †''C. spinosum'' Agassiz, 1833 - Ypresian of Monte Bolca, Italy (not recognized in more recent reviews) An indeterminate species is known from the Lutetian-aged Lutetian limestone of France. As its name suggests, ''C. gigas'' was a large fish that could reach up t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
List Of Prehistoric Bony Fish Genera
This list of prehistoric bony fish is an attempt to create a comprehensive listing of all genera from the fossil record that have ever been considered to be bony fish (class Osteichthyes), excluding purely vernacular terms. The list includes all commonly accepted genera, but also genera that are now considered invalid, doubtful (''nomina dubia''), or were not formally published ('' nomina nuda''), as well as junior synonyms of more established names, and genera that are no longer considered members of osteichthyes. This list includes 1,387 generic names. *Extinct genera are marked with a dagger (†). *Extant genera are bolded. Naming conventions and terminology Naming conventions and terminology follow the International Code of Zoological Nomenclature. Technical terms used include: * Junior synonym: A name which describes the same taxon as a previously published name. If two or more genera are formally designated and the type specimens are later assigned to the same genus, the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
