Turkmene
''Turkmene finitimus'' is an extinct lamprid from the Danata Formation Lagerstatten, of the Upper Paleocene of Turkmenistan. It lived sympatrically with its close relative, '' Danatinia''. In life, ''T. finitimus'' would have resembled a spadefish with beak-like lips, or a very small opah (its closest living relative) with a bulging forehead.

Danata Formation
The Danata Formation (or Danatinskaya, Danatinsk, Russian: Danata Svita) is an Ypresian, earliest Eocene to Middle Eocene sedimentary succession located in Turkmenistan. It is mostly famous for its fish-bearing horizons (Ichthyofauna). The formation for example crops out in the Kopet Dag mountain range in the border region of Turkmenistan and Iran. It was deposited in a far northeastern arm of the Tethys Ocean, Tethys Sea. Previously, it was thought that the earliest horizons of this formation dated to the latest Paleocene (Thanetian). However, more recent studies have found the formation's sapropel to originate from a global anoxic event caused by the Paleocene–Eocene Thermal Maximum, Paleocene-Eocene Thermal Maximum, indicating that it formed just after the Paleocene-Eocene boundary, during the earliest Ypresian. Paleoenvironment The Danata Formation is famous for its ichthyofauna. The fish are found in a thick clay horizon in the middle of the succession, that has been dat ...

Turkmenistan
Turkmenistan is a landlocked country in Central Asia bordered by Kazakhstan to the northwest, Uzbekistan to the north, east and northeast, Afghanistan to the southeast, Iran to the south and southwest and the Caspian Sea to the west. Ashgabat is the capital and largest city. It is one of the six independent Turkic states. With a population over 7 million, Turkmenistan is the 35th most-populous country in Asia and has the lowest population of the Central Asian republics while being one of the most sparsely populated nations on the Asian continent. Turkmenistan has long served as a thoroughfare for several empires and cultures. Merv is one of the oldest oasis-cities in Central Asia, and was once among the biggest cities in the world. It was also one of the great cities of the Islamic world and an important stop on the Silk Road. Annexed by the Russian Empire in 1881, Turkmenistan figured prominently in the anti-Bolshevik movement in Central Asia. In 1925, Turkmenistan be ...

Turkmenidae
Turkmenidae is an extinct family of lamprids from the Paleogene of the west-central Asia, in what was formerly the Peri-Tethys Ocean. They were small, disk-shaped fish that bore a strong resemblance to their closest living relatives, the opahs. '' Turkmene'' and '' Danatinia'' are found in the Thanetian epoch (of the Paleocene) sections of the Danata Formation of Turkmenistan. '' Analectis'' is found in Late Oligocene strata in North Caucasus The North Caucasus, or Ciscaucasia, is a subregion in Eastern Europe governed by Russia. It constitutes the northern part of the wider Caucasus region, which separates Europe and Asia. The North Caucasus is bordered by the Sea of Azov and the B ..., Russia. After the extinction of '' Analectis'', Turkmenidae disappears from the fossil record. References Further reading * K. A. Monsch and A. F. Bannikov. 2011.

Lampriformes
Lampriformes is an order (biology), order of Actinopterygii, ray-finned fish. Members are collectively called lamprids (which is more properly used for the Opah, Lampridae) or lampriforms, and unite such open-ocean and partially Deep sea, deep-sea Teleostei as the crestfishes, oarfish, opahs, and ribbonfishes. A synonym (biology), synonym for this order is Allotriognathi, while an often-seen, but apparently incorrect, spelling variant is Lampridiformes. They contain seven extant family (biology), families which are generally small but highly distinct, and a mere 12 lampriform genera with some 20 species altogether are recognized. They are the only extant members of the superorder Lamprimorpha, which was formerly diverse throughout much of the Late Cretaceous. The Binomial nomenclature, scientific name literally means "shaped (like the) bright (one)", as "lampr-", meaning bright, comes from ''lampris'', the generic name for the opah. In contrast, most other living lampriforms are ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Danatinia
''Danatinia'' is an extinct genus of lamprid fish from the Eocene. It contains a single species, ''D. casca'' from Danata Formation Lagerstatten, of the earliest Ypresian of Turkmenistan. It was first named by Daniltshenko in 1968. ''D. casca'' was sympatric with its close relative, '' Turkmene''. In life, it would have resembled a very small opah.

Thanetian
The Thanetian is, in the International Commission on Stratigraphy, ICS Geologic timescale, the latest age (geology), age or uppermost stage (stratigraphy), stratigraphic stage of the Paleocene epoch (geology), Epoch or series (stratigraphy), Series. It spans the time between . The Thanetian is preceded by the Selandian Age and followed by the Ypresian Age (part of the Eocene). The Thanetian is sometimes referred to as the Late Paleocene. Stratigraphic definition The Thanetian was established by Switzerland, Swiss geologist Eugène Renevier in 1873. The Thanetian is named after the Thanet Formation, the oldest Cenozoic deposit of the London Basin, which was first identified in the area of Kent (southern England) known as the Isle of Thanet. The base of the Thanetian Stage is laid at the base of magnetic chronozone C26n. The references profile (Global Boundary Stratotype Section and Point) is in the Zumaia section (43° 18'N, 2° 16'W) at the beach of Itzurun, Pais Vasco, northern ...

Paleocene
The Paleocene ( ), or Palaeocene, is a geological epoch (geology), epoch that lasted from about 66 to 56 mya (unit), million years ago (mya). It is the first epoch of the Paleogene Period (geology), Period in the modern Cenozoic Era (geology), Era. The name is a combination of the Ancient Greek ''palaiós'' meaning "old" and the Eocene Epoch (which succeeds the Paleocene), translating to "the old part of the Eocene". The epoch is bracketed by two major events in Earth's history. The K–Pg extinction event, brought on by an asteroid impact (Chicxulub impact) and possibly volcanism (Deccan Traps), marked the beginning of the Paleocene and killed off 75% of species, most famously the non-avian dinosaurs. The end of the epoch was marked by the Paleocene–Eocene Thermal Maximum (PETM), which was a major climatic event wherein about 2,500–4,500 gigatons of carbon were released into the atmosphere and ocean systems, causing a spike in global temperatures and ocean acidification. ...

Sympatric
In biology, two closely related species or populations are considered sympatric when they exist in the same geographic area and thus frequently encounter each other. An initially interbreeding population that splits into two or more distinct species sharing a common range exemplifies sympatric speciation. Such speciation may be a product of reproductive isolation – which prevents hybrid offspring from being viable or able to reproduce, thereby reducing gene flow – that results in genetic divergence. Sympatric speciation may, but need not, arise through secondary contact, which refers to speciation or divergence in allopatry followed by range expansions leading to an area of sympatry. Sympatric species or taxa in secondary contact may or may not hybrid (biology), interbreed. Types of populations Four main types of population pairs exist in nature. Sympatric populations (or species) contrast with parapatric populations, which contact one another in adjacent but not sh ...

Spadefish
Ephippidae is a family of percomorph fishes, the spadefishes, in the order Moroniformes. These fishes are found in the tropical and temperate oceans of the world, except for the central Pacific. Taxonomy Ephippidae was first proposed as a family in 1859 by the Dutch herpetologist and ichthyologist Pieter Bleeker. The 5th edition of the ''Fishes of the World'' classifies this family in the order Moroniformes with the Moronidae and Drepaneidae. Other authorities place this family alongside the Drepaneidae in the order Ephippiformes with the Moronidae classified as ''incertae sedis'' in the series Eupercaria. Other authorities classify all three families in the Moroniformes ''sensu'' ''Fishes of the World'' in the Acanthuriformes. Genera Ephippidae contains the following genera, 8 extant and 3 extinct ( means extinct): The extinct genus '' Exellia'' is classified within the Ephippidae by some authorities, other authorities place it in the family Exellidae.

Opah
The opah, also commonly known as moonfish, sunfish (not to be confused with Molidae), cowfish, kingfish, and redfin ocean pan are large, colorful, deep-bodied Pelagic zone, pelagic lampriform Fish, fishes comprising the genus ''Lampris'', of the small Family (biology), family Lampridae (also spelled Lamprididae). Species Two living species were traditionally recognized, but a Taxonomy (biology), taxonomic review in 2018 suggests the idea of splitting ''L. guttatus'' into several species, each with a more restricted geographic range, bringing the total to six. The six species of ''Lampris'' have mostly non-overlapping geographical ranges, and can be recognized based on body shape and coloration pattern. *Southern Spotted Opah (''Lampris australensis):'' Found in the southern hemisphere, primarily in the Pacific Ocean, Pacific and Indian Ocean, Indian oceans. *North Atlantic Opah (''Lampris guttatus):'' Potentially located in the Northeastern Atlantic, including the Medit ...

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 ...
