Description

Spathiurus was designated as a member of the family Ionoscopidae in 2020, as it shows the diagnostic features of the group, making it the first member of the family to be known from the late Cretaceous as well as the Middle East. [2] It is believed to be a sister taxon to Ionoscopus petrarojae, the both are more derived than 'Ionoscopus' cyprinoides, which probably belongs in a different distinct genus. [2] The species Amphilaphurus major is currently believed synonymous with Spathiurus dorsalis. [2]

Plectocretacicus is an extinct genus of prehistoric ray-finned fish that lived during the lower Cenomanian. It contains a single species, P. clarae. Plectocretacicus is the earliest known member of the order Tetraodontiformes.

<i>Coccodus</i> Extinct genus of fishes

Coccodus is an extinct genus of marine pycnodontid fish that lived during the Late Cretaceous. The various species had a pair of massive, curved spines emanating from the lower sides of the head, and one curved spine on the top of its head. Unlike most pycnodontids, Coccodus species had a comparatively long body, giving the living animals a superficial resemblance to a scaly chimaera.

<i>Aphanepygus</i> Extinct genus of fishes

Aphanepygus is an extinct genus of prehistoric marine holostean ray-finned fish that lived during the upper Cenomanian. It inhabited the former Tethys Ocean, with remains known from Lebanon and Croatia. Its exact affinities are uncertain, although it is usually recovered as a relative of the macrosemiids. However, other authorities recover it in the Ionoscopiformes.

Chanopsis is an extinct genus of prehistoric freshwater bonytongue relative that lived from the late Aptian to the Albian stage of the Early Cretaceous epoch. It contains a single species, C. lombardi from the Democratic Republic of the Congo.

Dactylopogon is an extinct genus of prehistoric marine ray-finned fish that lived during the Late Cretaceous. It contains a single species, D. grandis from the Campanian of the Ahlen Formation of Germany. It was previously considered a myctophiform, but more recent studies have found it to be an elopomorph. A second species, D. parvulus from the Cenomanian-aged Sannine Formation in Lebanon has also sometimes been placed in this genus.

Cryptoberyx is an extinct genus of prehistoric marine ray-finned fish that lived during the late Cenomanian stage of the Late Cretaceous. Two species are known from southern Europe and the Middle East, both part of the former Tethys Sea.

<i>Lissoberyx</i> Extinct genus of fishes

Lissoberyx is an extinct genus of prehistoric ray-finned fish belongon to the family Trachichthyidae. Lissoberyx is a trachichthyid, but it shows more resemblance to the holocentrids than any other trachichthyid.

Mesoclupea showchangensis is an extinct ichthyodectiform ray-finned fish that lived in freshwater environments in what is now China during the Early Cretaceous epoch. It differs from its sister genus, Chuhsiungichthys, primarily by having a more posteriorly-placed dorsal fin.

<i>Amiopsis</i> Extinct genus of fishes

Amiopsis is an extinct genus of prehistoric freshwater and marine bony fish belonging to the family Amiidae, making it closely related to the modern bowfin. Fossils are known from the Late Jurassic Solnhofen Limestone, Germany, the Early Cretaceous Purbeck Group, England, La Pedrera de Rúbies Formation, Spain and Bernnissant Iguanodon locality, Belgium and the Late Cretaceous (Cenomanian) of the Balkans. The monophyly of the genus is questionable, due to it being based on a single character, "the presence of three or more lateral fossae on each side of most abdominal centra". Remains previously assigned to this genus from the Early Cretaceous Las Hoyas, Spain have been moved into the new genus Hispanamia.
