Iberomesornis is a monotypic genus of enantiornithine bird of the Cretaceous of Spain.
Eoalulavis is a monotypic genus of enantiornithean bird that lived during the Barremian, in the Lower Cretaceous around 125 million years ago. The only known species is Eoalulavis hoyasi.
Holophagus is an extinct genus of coelacanth belonging to Latimeriidae. The type species, Holophagus gulo, is known from the Lower Jurassic marine Lias of England. Some authors have considered the genus restricted to the Lias of England.
The La Huérguina Formation is a geological formation in Spain whose strata date back to the Barremian stage of the Early Cretaceous. Las Hoyas is a Konservat-Lagerstätte within the formation, located near the city of Cuenca, Spain. The site is mostly known for its exquisitely preserved dinosaurs, especially enantiornithines. The lithology of the formation mostly consists of lacustrine limestone deposited in a freshwater wetland environment.
Valdotriton is a genus of extinct prehistoric salamanders. Its only known species is Valdotriton gracilis. V. gracilis lived during the Late Barremian in what is now Spain. It was found in the Las Hoyas locality. It represents one of the oldest known members of Salamandroidea.
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.
Dastilbe is an extinct genus of prehistoric marine & freshwater ray-finned fish from the Early Cretaceous of Brazil. It was a relative of modern milkfish.
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.
Casierius is an extinct genus of marine ray-finned fish that lived during the Albian stage of the Early Cretaceous epoch. It was a relative of the modern bonefish in the extinct family Phyllodontidae, although some authorities consider it either a true albulid or a very early eel. It contains a single species, C. heckeli, known from the Glen Rose Formation near Hood County, Texas.
Flindersichthys is an extinct genus of prehistoric bony fish that lived during the Albian stage of the Early Cretaceous epoch.
Stromerichthys is an extinct genus of potentially chimaeric freshwater bony fish that lived during the Late Cretaceous epoch. It contains a single species, S. aethiopicus, described from a now-lost specimen with bones & scales from Egypt.
Aethalionopsis is an extinct genus of prehistoric freshwater bony fish from the Early Cretaceous of western Europe. Formerly classified as a species of the elopiform Anaethalion, it is now known to be a relative of the modern milkfish (Chanos) in order Gonorhynchiformes. It was previously placed as a basal member of the suborder Chanoidei, but is now more often placed as a basal member of the subfamily Chaninae of the family Chanidae, placing it closer to the extant Chanos.
Anaethalion is an extinct genus of prehistoric marine and freshwater ray-finned fish related to modern tarpons and ladyfish. It is known from the Late Jurassic to the Early Cretaceous of Europe and northeasterrn Asia, roughly encompassing the Tethys Ocean.
Athrodon is an extinct genus of marine pycnodontid fish that lived in shallow seas in what is now England, Germany, Spain and France from the Late Jurassic until the genus' extinction during the start of the late Cretaceous. The various species are very similar in splenial bone and tooth morphology to Mesodon. Otherwise, no articulated or complete specimen is known: all fossil specimens are bone fragments and disarticulated teeth. This genus is thought to be diagnosed by the presence of four lateral tooth rows. The presence of this genusin the Cretaceous is disputed, as the remains of Cretaceous species could belong to other genera.
Brannerion is an extinct genus of prehistoric marine bonefish. Fossils of the genus were found in the Romualdo Formation of the Santana Group, Araripe Basin, northeastern Brazil. It is considered a basal member of the Albuliformes.
Cylindracanthus is an extinct, enigmatic genus of marine ray-finned fish with fossils known throughout North America, Europe, Asia and Africa from the Late Cretaceous to the late Eocene, with potential Oligocene records and a possible Miocene record also known. It is exclusively known from its distinctive partial remains, which are long cylindrical bony spines that are usually considered rostrum fragments, as well as some associated teeth. These spines are abundant & widespread throughout this timespan, and are useful indicators of a nearshore marine environment, but the taxonomic identity of the fish is still highly uncertain and debated.
Gyronchus is an extinct genus of prehistoric ray-finned fish from the Jurassic. This genus is currently treated as a wastebasket taxon used for pycnodonts like Macromesodon and Turbomesodon.
Psilichthys is an extinct genus of prehistoric bony fish from Eumeralla Formation, the Lower Cretaceous epoch of what is now Victoria, Australia, known from single species P. selwyni. This is the first Mesozoic fossil vertebrate named from Victoria.
Egertonia is an extinct genus of prehistoric bony fish. The earliest occurrences of the genus in the fossil record are from the Late Cretaceous of Madagascar and India.
Morrolepis is an extinct genus of prehistoric coccolepidid "palaeoniscoid" ray-finned fish that lived during the Late Jurassic and earliest Cretaceous epochs in Europe, Asia and North America.
