Sorbinichthys
''Sorbinichthys'' is a genus of extinct ray-finned fish from the Cenomanian of Lebanon and Morocco. It is classified within the order Ellimmichthyiformes. Both species within the genus are small (15 cm) and, like other members of their order, have deep bodies. The most notable feature of the genus is the presence of extremely long 2nd fin rays on the dorsal and pectoral fins that are much longer than the other rays on the respective fins. ''Sorbinichthys'' is one of the most basal members of the order and, in some analyes, the sister group of the rest of the order. The fish lived in shallow coastal environments that were home to a number of other fish and invertebrates. Two species are currently recognized: ''S. elusivo'' and ''S. africanus''. History and naming The type species of ''Sorbinichthys'' was described in 2000 by Bannikov & Bacchia based on material found within the Nammoura locality, within Lebanon. This description was based on the holotype specimen (CLC No. 431) alo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

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] |
Gasteroclupea Branisai
''Gasteroclupea'' is a genus of prehistoric ellimmichthyiform fish that is distantly related to modern anchovies and herrings. It contains one species, ''G. branisai''. It inhabited freshwater or estuarine habitats across South America during the Campanian and Maastrichtian stages of the Late Cretaceous period, and it briefly survived beyond the K-Pg boundary into the Danian stage of the Paleocene, making it among the few genera from its order to survive into the Cenozoic. Fossils of the genus have been found in the Yacoraite Formation of Argentina, the Chaunaca Formation, Santa Lucía Formation, and El Molino Formation of Bolivia, and the Navay Formation in Venezuela. Its taxonomic identity was long uncertain, often being placed as a clupeid or an indeterminate clupeomorph, but more recent studies have placed it with the Ellimmichthyiformes. Its closest relative has been found to be ''Sorbinichthys'', another unusual ellimmichthyiform from marine deposits in Lebanon, thoug ...

Diplomystus Dubertreti
''Diplomystus'' is an extinct genus of freshwater and marine clupeomorph fish distantly related to modern-day extant herrings, anchovies, and sardines. It is known from the United States, China, and Lebanon from the Late Cretaceous to the middle Eocene. Many other clupeomorph species from around the world were also formerly placed in the genus, due to it being a former wastebasket taxon. It was among the last surviving members of the formerly-diverse order Ellimmichthyiformes, with only its close relative '' Guiclupea'' living for longer. Taxonomy The genus contains the following species: * ''D. birdi'' Woodward, 1895 – Late Cretaceous (Cenomanian) of Lebanon (Sannine Formation) * ''D. dentatus'' Cope, 1877 – Early Eocene of Wyoming, USA (Green River Formation) * ''D. dubertreti'' Signeux, 1951 – Late Cretaceous (Santonian) of Lebanon ( Sahel Alma) * ''D. shengliensis'' Zhang, Zhou & Qing, 1985 – Middle Eocene (Bartonian) of China ( Shahejie Formation) The type spe ...
