Oligolophotes
''Oligolophotes'' is an extinct genus of fish from the Early Oligocene of the bank of Belaya River in Adygea, the Caucasus Mountains. There is one species, ''Oligolophotes fragosus'', known from the holotype A holotype is a single physical example (or illustration) of an organism, known to have been used when the species (or lower-ranked taxon) was formally described.

Lophotidae
Crestfishes, family Lophotidae, are lampriform fishes found in most oceans. It consists of two extant and four extinct genera. They are elongated, ribbon-like fishes, silver in color, found in deep tropical and subtropical waters worldwide. Their scientific name is from Greek ''lophos'' meaning "crest" and refer to the crest (part of the dorsal fin) that emerges from the snout and head; this structure gives them their other name of unicorn fishes. The extant genera all possess ink sacs that open into their cloacae from which they can produce a cloud of black ink when threatened (as in many cephalopod A cephalopod is any member of the molluscan class Cephalopoda (Greek plural , ; "head-feet") such as a squid, octopus, cuttlefish, or nautilus.

Fish
Fish are aquatic, craniate, gill-bearing animals that lack limbs with digits. Included in this definition are the living hagfish, lampreys, and cartilaginous and bony fish as well as various extinct related groups. Approximately 95% of living fish species are ray-finned fish, belonging to the class Actinopterygii, with around 99% of those being teleosts. The earliest organisms that can be classified as fish were soft-bodied chordates that first appeared during the Cambrian period. Although they lacked a true spine, they possessed notochords which allowed them to be more agile than their invertebrate counterparts. Fish would continue to evolve through the Paleozoic era, diversifying into a wide variety of forms. Many fish of the Paleozoic developed external armor that protected them from predators. The first fish with jaws appeared in the Silurian period, after which many (such as sharks) became formidable marine predators rather than just the prey of arthropods. Mos ...

Oligocene
The Oligocene ( ) is a geologic epoch of the Paleogene Period and extends from about 33.9 million to 23 million years before the present ( to ). As with other older geologic periods, the rock beds that define the epoch are well identified but the exact dates of the start and end of the epoch are slightly uncertain. The name Oligocene was coined in 1854 by the German paleontologist Heinrich Ernst Beyrich from his studies of marine beds in Belgium and Germany. The name comes from the Ancient Greek (''olígos'', "few") and (''kainós'', "new"), and refers to the sparsity of extant forms of molluscs. The Oligocene is preceded by the Eocene Epoch and is followed by the Miocene Epoch. The Oligocene is the third and final epoch of the Paleogene Period. The Oligocene is often considered an important time of transition, a link between the archaic world of the tropical Eocene and the more modern ecosystems of the Miocene. Major changes during the Oligocene included a global expansion o ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Belaya River (Kuban)
The Belaya (russian: Бе́лая; ady, Шъхьагуащэ, Ŝhagwaśæ ) is a river in the Republic of Adygea and Krasnodar Krai of Russia. It is a left tributary of the Kuban, which it joins in the Krasnodar Reservoir. The river is long, with a drainage basin of . It has its sources at the main watershed of the Caucasus Mountains. In its upper reaches it is a typical mountain river, and flows through deep canyons, while in its lower parts it is a slow flowing lowland river. Its main tributaries are, from source to mouth, Kisha (right), Dakh (right), Kurdzhips (left) and Pshekha (left). Several cities and towns are located along the river including Maykop and Belorechensk Belorechensk may refer to: *Belorechensk, Krasnodar Krai, a town in Krasnodar Krai, Russia * Belorechensk, Kirov Oblast, a former urban-type settlement in Kirov Oblast Kirov Oblast (russian: Ки́ровская о́бласть, ''Kirovskaya oblas ....

Adygea
The Republic of Adygea (; russian: Республика Адыгея, Respublika Adygeya, p=ɐdɨˈɡʲejə; ady, Адыгэ Республик, ''Adıgə Respublik''), also known as the Adyghe Republic, is a republic of Russia. It is situated in the North Caucasus of Eastern Europe. The republic is a part of the Southern Federal District, and covers an area of , with a population of roughly 496,934 residents. It is an enclave within Krasnodar Krai and is the fifth-smallest Russian federal subject by area. Maykop is the capital and the largest city of Adygea, home to one-third of the republic's population. Adygea is one of Russia's ethnic republics, primarily representing the indigenous Circassian people that form 25% of the Republic's population, while Russians form a majority at 60%, and with minority populations of Armenians and Ukrainians. The official languages of Adygea are Russian and Adyghe. Geography Adygea lies in Russia's Southern Federal District of Eastern Europe, ...

Caucasus Mountains
The Caucasus Mountains, : pronounced * hy, Կովկասյան լեռներ, : pronounced * az, Qafqaz dağları, pronounced * rus, Кавка́зские го́ры, Kavkázskiye góry, kɐfˈkasːkʲɪje ˈɡorɨ * tr, Kafkas Dağları, * fa, كوه هاى قفقاز are a mountain range at the intersection of Asia and Europe. Stretching between the Black Sea and the Caspian Sea, they are surrounded by the Caucasus region and are home to Mount Elbrus, the list of elevation extremes by region, highest peak in Europe at above sea level. The Caucasus Mountains include the Greater Caucasus in the north and Lesser Caucasus in the south. The Greater Caucasus runs west-northwest to east-southeast, from the Western Caucasus, Caucasian Natural Reserve in the vicinity of Sochi, Russia on the northeastern shore of the Black Sea to Baku, Azerbaijan on the Caspian Sea. The Lesser Caucasus runs parallel to the Greater about south. The Greater and Lesser Caucasus ranges are co ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Holotype
A holotype is a single physical example (or illustration) of an organism, known to have been used when the species (or lower-ranked taxon) was formally described. It is either the single such physical example (or illustration) or one of several examples, but explicitly designated as the holotype. Under the International Code of Zoological Nomenclature (ICZN), a holotype is one of several kinds of name-bearing types. In the International Code of Nomenclature for algae, fungi, and plants (ICN) and ICZN, the definitions of types are similar in intent but not identical in terminology or underlying concept. For example, the holotype for the butterfly '' Plebejus idas longinus'' is a preserved specimen of that subspecies, held by the Museum of Comparative Zoology at Harvard University. In botany, an isotype is a duplicate of the holotype, where holotype and isotypes are often pieces from the same individual plant or samples from the same gathering. A holotype is not necessarily "typ ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
