Rhamphoichthys
''Rhamphoichthys'' is an Extinction, extinct genus of billfish-like Plethodidae, plethodid Actinopterygii, ray-finned fish from Late Cretaceous (Cenomanian). It contains one valid species, ''R. taxidiotis'' from the Hesseltal Formation of Germany and the Sannine Formation of Lebanon, in addition to two dubious species (''R. minor'' from England and ''R. stebbingi'' from England & Italy) that are considered Nomen nudum, ''nomina nuda'' due to their fragmentary nature. ''Rhamphoichthys'' was a large, streamlined Tselfatiiformes, tselfatiiform fish with an elongated Rostrum (anatomy), rostrum, akin to those of modern billfish and the co-occurring Pachycormiformes, pachycormid fish ''Protosphyraena''; the English and Italian species are only known from rostral fragments that were previously assigned to ''Protosphyraena''. It is one of the few longirostrine tselfatiiforms known, alongside the more fragmentary ''Martinichthys'' from North America. ''Rhamphoichthys'' rostra can be differe ...

Plethodidae
Plethodidae is an extinct Family (biology), family of Teleostei, teleost fish that existed during the Late Cretaceous period. Fossils are known from North America, North Africa, and Europe. Description Plethodids possessed thin, Pomacanthidae, angelfish-like bodies and often had high dorsal fins which made them distinctive from other types of fish. Their skeletons were partially cartilage, cartilaginous, though the amount varied from one species to another.
