Ellimmichthys
''Ellimmichthys'' is an extinct genus of freshwater Otocephala, clupeomorph fish belonging to the order Ellimmichthyiformes, of which it is the type genus. It was a distant relative of modern herrings and Anchovy, anchovies. It inhabited freshwater rift lakes in the supercontinent of Gondwana, West Gondwana (comprising modern South America and Africa) during the Early Cretaceous, and fossil remains are known from formations in both South America (Brazil) and Africa (Equatorial Guinea). Taxonomy The following species are known: * †''E. longicostatus'' (Edward Drinker Cope, Cope, 1886) - Berriasian/Valanginian of Bahia, Brazil (Candeias Formation) (=''Diplomystus longicostatus'' Cope, 1886) (type species) * †''E. goodi'' (Charles R. Eastman, Eastman, 1912) - Aptian/Albian of Equatorial Guinea (Cocobeach Formation) (=''Diplomystus goodi'' Eastman, 1912, ''D. elberti'' Weiler, 1922, ''Ellimma guineensis'' Gayet, 1989) * †''E. spinosus'' de Figuereido & Gallo, 2021 - Berriasia ...

Ellimmichthyiformes
The Ellimmichthyiformes, also known as double-armored herrings, are an Extinction, extinct Order (biology), order of Actinopterygii, ray-finned fish known from the Early Cretaceous to the Oligocene. They were the sister group to the extant true herrings, Alosidae, shad and Anchovy, anchovies in the order Clupeiformes, with both orders belonging to the suborder Clupeomorpha. A highly successful group throughout the Cretaceous, they were found worldwide and are known to have inhabited both marine and freshwater habitats. They appear to have been a largely marine group for most of their history, with the first freshwater lineages appearing during the Late Cretaceous. Shortly after the origin of the Ellimmichthyiformes in the Early Cretaceous, the Mediterranean Sea, Mediterranean portion of the Tethys Ocean appears to have been a major center of diversification for them, as the majority of fossils of this group are known from there. Following this, they saw an explosion in diversity ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
