Cheirothricidae
Cheirothricidae is a family of extinct marine ray-finned fish, perhaps belonging to the Aulopiformes, although they are tentatively placed as indeterminate eurypterygians. They lived during the Upper Cretaceous (Cenomanian - Campanian, about 95 - 71 million years ago) and their fossil remains are found in the Middle East and Europe. They were characterized by very expanded even fins. Genera *†'' Cheirothrix'' Pictet and Humbert, 1866 - Late Santonian to Campanian of Germany and Lebanon *†'' Exocoetoides'' Davis, 1887 - Late Cenomanian of Lebanon *?†'' Telepholis'' von der Marck, 1868 - Late Campanian of Germany (possibly a stem- stomiiform) Description The main characteristic of these small fish (the length of the body was usually between 3 and 20 centimeters in length) was given by the extreme development of the even fins; in '' Cheirothrix'' species the pectoral fins were particularly developed, while in '' Telepholis'' and '' Exocoetoides'' also the pelvic fins were lar ...

Aulopiformes
Aulopiformes is a diverse order (biology), order of Marine (ocean), marine ray-finned fish consisting of some 15 Extant taxon, extant and several prehistoric family (biology), families with about 45 genera and over 230 species. The common names grinners, lizardfishes and allies, or aulopiforms are sometimes used for this group. They are included in the superorder Cyclosquamata, though modern taxonomists consider this superorder to be unwarranted. Many Neontology, extant aulopiforms are deep-sea fishes, with some species recognized as being hermaphroditic, a number of which are able to Autogamy, self-fertilise. Some are benthic, but most are pelagic swimmers (nektonic). A clade of Aulopiformes, the suborder Enchodontoidei and its many constituent families, were dominant nektonic fish throughout much of the Late Cretaceous before the extinction of most of their members around the K–Pg event, with the Dercetidae surviving for some time in the Cenozoic.

Flying Fish
The Exocoetidae are a family (biology), family of Saltwater fish, marine Actinopterygii, ray-finned fish in the order (biology), order Beloniformes, known colloquially as flying fish or flying cod. About 64 species are grouped in seven genus, genera. While they do not "fly" in the same way a bird does, flying fish can make powerful leaps out of the water where their long wing-like fins enable gliding flight, gliding for considerable distances above the water's surface. The main reason for this behavior is thought to be to escape from underwater predators, which include swordfish, mackerel, tuna, and marlin, among others, though their periods of flight expose them to attack by avian predators such as frigate birds. Barbados is known as "the land of the flying fish" and the fish is one of the national symbols of the country. The Exocet missile is named after them, as variants are launched from underwater, and take a low trajectory, skimming the surface, before striking their target ...

Exocoetoides
''Exocoetoides'' is an extinct genus of prehistoric marine ray-finned fish from the Late Cretaceous. The genus name is derived from its resemblance to ''Exocoetus'', a modern-day flying fish. It contains a single species, ''E. minor'' Davis, 1887, known from the Cenomanian-aged Sannine Formation of Lebanon. "'' Engraulis evolans''" Agassiz, 1835 from the Early Eocene of Monte Bolca, Italy was also assigned to this genus by Gorjanovic-Kramberger (1895), although Grande (1985) found this species to most likely represent a juvenile true flying fish. Description ''Exocoetoides'' species could reach a body length of about . The main characteristic of these decidedly small fishes was given by the extreme development of the even fins. In particular, the pectoral fins were particularly long (they could reach the anal region). Also the pelvic fins were large. Moreover the fins were provided with very long rays. In the caudal fin both lobes were the same size. It differs from the clos ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Santonian
The Santonian is an age in the geologic timescale or a chronostratigraphic stage. It is a subdivision of the Late Cretaceous Epoch or Upper Cretaceous Series. It spans the time between 86.3 ± 0.7 mya ( million years ago) and 83.6 ± 0.7 mya. The Santonian is preceded by the Coniacian and is followed by the Campanian.Gradstein ''et al.'' (2004) Stratigraphic definition The Santonian Stage was established by French geologist Henri Coquand in 1857. It is named after the city of Saintes in the region of Saintonge, where the original type locality is located. The base of the Santonian Stage is defined by the appearance of the inoceramid bivalve ''Cladoceramus undulatoplicatus''. The GSSP (official reference profile) for the base of the Santonian Stage is located near Olazagutia, Spain; it was ratified by the Subcommission on Cretaceous Stratigraphy in 2012. The Santonian's top (the base of the Campanian Stage) is informally marked by the extinction of the crinoid '' ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Euteleostei Families
Euteleostei, whose members are known as euteleosts, is a clade of bony fishes within Teleostei that evolved some 240 million years ago, although the oldest known fossil remains are only from the Early Cretaceous. It is divided into Protacanthopterygii (including the salmon and dragonfish) and Neoteleostei (including the lanternfish, lizardfish, oarfish, and Acanthopterygii).

Thoracopterus
''Thoracopterus'' is an extinct genus of overwater gliding ray-finned fish from the Carnian age of the Late Triassic. It is a monotypic taxon, with the type species being ''T. niederristi''. ''Thoracopterus'' had elongate pectoral fins, similar to modern Exocoetidae, which are used to glide overwater in order to escape aquatic predators. ''Thoracopterus'' represents one of the earliest known example for overwater gliding in actinopterygians.

Enchodontidae
Enchodontidae is an extinct family of marine enchodontoid aulopiform ray-finned fish from the Cretaceous to potentially the Eocene, being found worldwide. The family itself was diverse within its body form though unlike other enchodontoids, most genera within the family possessed rows of scutes behind the head and sides of the body. Like a large amount of extinct groups, the origin of enchodontids have remained obscured though this is mostly due to a large diversification event that happened in the Late Aptian to Middle Cenomanian. Though the family is diverse in their range and anatomy, all known members were predatory with most living in more shallow, near-shore environments. History Though the family itself was erected in 1901, a number of members of the group were previously described by Agassiz and other authors. Remains of enchodontids where for a long time only known from North America and Europe and still very commonly found there. Over the last few decades, material has ...

Paleobiology Database
The Paleobiology Database (PBDB) is an online resource for information on the distribution and classification of fossil animals, plants, and microorganisms. History The Paleobiology Database originated in the NCEAS-funded Phanerozoic Marine Paleofaunal Database initiative, which operated from August 1998 through August 2000. From 2000 to 2015, PBDB received funding from the National Science Foundation. PBDB also received support form the Australian Research Council. From 2000 to 2010 it was housed at the National Center for Ecological Analysis and Synthesis, a cross-disciplinary research center within the University of California, Santa Barbara. It is currently housed at University of Wisconsin-Madison and overseen by an international committee of major data contributors. The Paleobiology Database works closely with the Neotoma Paleoecology Database, which has a similar intellectual history, but has focused on the Quaternary (with an emphasis on the late Pleistocene and Holoc ...
