Pentanogmius Evolutus
''Pentanogmius'' is an extinct genus of sail-finned ray-finned fish that lived during the Late Cretaceous in what is now Europe and the USA. Five species are currently recognized, 2 from Cenomanian to Turonian Europe and 3 better known species from Coniacian to Campanian North America. The American species inhabited large areas of the Western Interior Seaway, with fossil finds indicating a range from Texas and Alabama in the south to Manitoba, Canada, in the north. History and naming The first remains that now fall under the name ''Pentanogmius'' were found in the English Lower Chalk and described in 1850 as ''Plethodus pentagon''. In 1877 Edward Drinker Cope named ''Anogmius evolutus'' from a let mandibular ramus found in the Niobrara Formation of Kansas, taking note of its less curved morphology compared to the other ''Anogmius'' species known at the time. As ''Anogmius'' was preoccupied, the name was eventually changed to ''Ananogmius'' and then ''Bananogmius''. Later, ''Banano ...

Extinct
Extinction is the termination of a kind of organism or of a group of kinds (taxon), usually a species. The moment of extinction is generally considered to be the death of the last individual of the species, although the capacity to breed and recover may have been lost before this point. Because a species' potential range may be very large, determining this moment is difficult, and is usually done retrospectively. This difficulty leads to phenomena such as Lazarus taxa, where a species presumed extinct abruptly "reappears" (typically in the fossil record) after a period of apparent absence. More than 99% of all species that ever lived on Earth, amounting to over five billion species, are estimated to have died out. It is estimated that there are currently around 8.7 million species of eukaryote globally, and possibly many times more if microorganisms, like bacteria, are included. Notable extinct animal species include non-avian dinosaurs, saber-toothed cats, dodos, m ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Bananogmius
''Bananogmius'' is an extinct genus of ray-finned fish that lived in what is today Kansas during the Late Cretaceous. It lived in the Western Interior Seaway, which split North America in two during the Late Cretaceous.Fielitz C, Shimada K. 1999.

Description As with many plethodids, ''Bananogmius'' had a thin body reminiscent of the modern angelfish, dozens of small teeth, and an extremely high dorsal fin A dorsal fin is a fin located on the back of most marine and freshwater vertebrates within various taxa of the animal kingdom.

Protobrama
''Protobrama'' is an extinct genus of teleost fish from the Cretaceous period of Lebanon. ''Protobrama'' was a small fish, only long, and is thought to have hunted around coral reefs. It had a deep body, with long dorsal and anal fins, but had no pelvic fin. The position of the pectoral fin Fins are distinctive anatomical features composed of bony spines or rays protruding from the body of a fish. They are covered with skin and joined together either in a webbed fashion, as seen in most bony fish, or similar to a flipper, as ...s high on the body suggests that it was probably a fairly agile fish.

Paranogmius
''Paranogmius'' is an extinct genus of prehistoric bony fish that lived during the Cenomanian. It is known from only 2 partial skulls and several dorsal vertebrae discovered in the Bahariya Formation that was destroyed during World War II.Weiler, W.

Pachyrhizodus
''Pachyrhizodus'' is an extinct genus of ray-finned fish that lived during the Cretaceous to Paleocene in what is now Europe, North America, South America, and Oceania. Many species are known, primarily from the Cretaceous of England and the midwestern United States. History and discovery ''Pachyrhizodus'' fossils were first collected from Cambridgeshire, England in the 1840s and were very fragmentary, only a partial maxilla (SMB.9097) and were described as a species of ''Raphiosaurus'' in 1842 by Richard Owen. The type remains of ''Pachyrhizodus'' consisted of a maxilla (BMNH 49014) from the Lower Cretaceous of Sussex, England and was originally thought to be a mandible that Louis Agassiz dubbed ''Pachyrhizodus'' in 1850,Dixon, F. (1850): Geology and Fossils of the Tertiary and Cretaceous Formations of Sussex. – 422 pp.; London (Longman, Brown, Green & Longmans). with Frederick Dixon creating the species name ''basalis'' for the specimen.

Swordfish
Swordfish (''Xiphias gladius''), also known as broadbills in some countries, are large, highly migratory predatory fish characterized by a long, flat, pointed bill. They are a popular sport fish of the billfish category, though elusive. Swordfish are elongated, round-bodied, and lose all teeth and scales by adulthood. These fish are found widely in tropical and temperate parts of the Atlantic, Pacific, and Indian Oceans, and can typically be found from near the surface to a depth of , and exceptionally up to depths of 2,234 m. They commonly reach in length, and the maximum reported is in length and in weight.Gardieff, S. Swordfish.' Florida Museum of Natural History. Accessed 26 December 2011 They are the sole member of their family, Xiphiidae. Taxonomy and etymology The swordfish is named after its long pointed, flat bill, which resembles a sword. The species name, ''Xiphias gladius'', derives from Greek (''xiphias'', "swordfish"), itself from (''xiphos'', "sword") and ...

Marlin
Marlins are fish from the family Istiophoridae, which includes about 10 species. A marlin has an elongated body, a spear-like snout or bill, and a long, rigid dorsal fin which extends forward to form a crest. Its common name is thought to derive from its resemblance to a sailor's marlinspike. Marlins are among the fastest marine swimmers. However, greatly exaggerated speeds are often claimed in popular literature, based on unreliable or outdated reports. The larger species include the Atlantic blue marlin, ''Makaira nigricans'', which can reach in length and in weight and the black marlin, ''Istiompax indica'', which can reach in excess of in length and in weight. They are popular sporting fish in tropical areas. The Atlantic blue marlin and the white marlin are endangered owing to overfishing. Classification The marlins are Istiophoriform fish, most closely related to the swordfish, which is the sole member of Xiphiidae. The carangiformes is believed to be the second- ...
