Maraldichthys verticalis is a species of pycnodontiform fish of the family Gebrayelichthyidae, the only in the monotypic genus Maraldichthys. It lived during the Cenomanian of Lebanon. [1]
Libanopristis is an extinct genus of ganopristid sclerorhynchoid that lived in Lebanon during the Late Cretaceous.
Pycnodontiformes is an extinct order of primarily marine bony fish. The group first appeared during the Late Triassic and disappeared during the Eocene. The group has been found in rock formations in Africa, Asia, Europe, North and South America. They were small to middle-sized fish, generally with laterally-compressed deep bodies, some with almost circular outlines, adapted for manuverability in reef-like environments, though the group was morphologically diverse. Most, but not all members of the groups had jaws with round and flattened teeth, well adapted to crush food items (durophagy), such as echinoderms, crustaceans and molluscs. Some pyncodontiformes developed piranha like teeth used for eating flesh. Most species inhabited shallow marine reef environments, while a handful of species lived in freshwater or brackish conditions. While rare during the Triassic and Early-Middle Jurassic, Pycnodontiformes became abundant and diverse during the Late Jurassic, exhibitng a high but relatively static diversity during the Early Cretaceous. At the beginning of the Late Cretaceous they reached their apex of morphological and species diversity, after which they began to gradually decline, with a more sudden decline at the end of the Cretaceous due to the collapse of reef ecosystems, finally becoming extinct during the Eocene. They are considered to belong to the Neopterygii, but their relationship to other members of that group is uncertain.
Trewavasia carinata is an extinct pycnodontid fish in the family Coccodontidae that lived during the lower Cenomanian of what is now Lebanon. It had a large, forward-pointing horn-like spine between its eyes, and a massive stump-like spine emanating from the back of its head. T. carinata is closely related the genera Corusichthys and Hensodon, as well as Coccodus.
Coccodus is an extinct genus of extinct pycnodontid fish that lived during the lower Cenomanian. 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.
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.
Halecostomi is the name of a group of neopterygian fish uniting the halecomorphs and the teleosts, the largest group of extant ray-finned fish.
Ligulella is an extinct genus of ray-finned fish that lived in what is now the Democratic Republic of the Congo during the Middle Jurassic epoch. It contains one species, Ligulella sluysi. Ligulella is the only member of the family Ligulellidae and the order Ligulelliformes.
The Solnhofen Plattenkalk, a collective term of multiple Late Jurassic lithographic limestones in southeastern Germany, is famous for its well preserved fossil flora and fauna dating to the late Jurassic.
Coccodontidae is a family of extinct pycnodontid fish that lived during the lower Cenomanian. The various genera had massive, curved spines.
Gyrodactylidae is a family of flatworms in the order Gyrodactylidea.
Opecoelidae is a family of trematodes. It is the largest digenean family with over 90 genera and nearly 900 species, almost solely found in marine and freshwater teleost fishes. It was considered by Bray et al. to belong in the superfamily Opecoeloidea Ozaki, 1925 or the Brachycladioidea Odhner, 1905.
Micropristis is an extinct genus of ganopristid sclerorhynchoid that lived in the Middle East and Europe during the Late Cretaceous.
John Ernest "Jack" Randall was an American ichthyologist and a leading authority on coral reef fishes. Randall described over 800 species and authored 11 books and over 900 scientific papers and popular articles. He spent most of his career working in Hawaii. He died in April 2020 at the age of 95.
Halecomorphi is a taxon of ray-finned bony fish in the clade Neopterygii. The only extant Halecomorph species are the bowfin and eyespot bowfin, but the group contains many extinct species in several families in the order Amiiformes, as well as the extinct orders Ionoscopiformes, Panxianichthyiformes, and Parasemionotiformes. The fossil record of halecomorphs goes back at least to the Early Triassic epoch.
This list of fossil fishes described in 2014 is a list of new taxa of placoderms, fossil cartilaginous fishes and bony fishess of every kind that have been described during the year 2014, as well as other significant discoveries and events related to paleontology of fishes that occurred in the year 2014. The list only includes taxa at the level of genus or species.
Agonomalus proboscidalis is a fish in the family Agonidae. It was described by Achille Valenciennes in 1858, originally under the genus Aspidophorus. It is a marine, polar water-dwelling fish which is known from the northwestern Pacific Ocean, including northern Japan, the Sea of Japan, and the Sea of Okhotsk. It is known to dwell at a depth range of 20 to 102 metres. Males can reach a maximum total length of 20 centimetres (7.9 in).
The Sannine Formation, also called the Sannine Limestone, is a Cretaceous geologic formation in Lebanon.
Pseudocorax is an extinct genus of mackerel sharks that lived during the Late Cretaceous. It contains six valid species that have been found in Europe, the Middle East, North Africa, and North America. It was formerly assigned to the family Anacoracidae, but is now placed in its own family Pseudocoracidae along with Galeocorax. The former species "P." australis and "P." primulus have been reidentified as species of Echinorhinus and Squalicorax, respectively.
Corusichthys megacephalus is an extinct pycnodontid that lived during the lower Cenomanian of what is now Lebanon. C. megacephalus is known from a 34 mm long fossil. It had plates arranged like a helmet around its head, and had a massive, triangular spine on its dorsal side. C. megacephalus is closely related the genera Trewavasia and Hensodon, as well as Coccodus.
Gebrayelichthyidae is a family of extinct pycnodontid fish, with a superficially shrimpfish-like appearance that lived during the lower Cenomanian.
