Tadzhikosuchus
''Tadzhikosuchus'' is an extinct genus of neosuchian crocodyliform from the Late Cretaceous of Tajikistan. Three species have been named: the type species ''T. macrodentis'', described by Efimov in 1982 from the lower Santonian-age Upper Cretaceous Ialovachsk Formation of Kansai, Tajikistan, in the Fergana Basin of Tajikistan; ''T. neutralis'' from the same location, by Efimov in 1988; and ''T. kizylkumensis'' from Turonian-age rocks of the Upper Cretaceous Bissekty Formation of Dzharakhuduk, Uzbekistan, by Nesov and colleagues in 1989. However, a 2000 review by Glenn Storrs and Mikhail Efimov could not differentiate between the species based on their type material, and recommended grouping the specimens of all three species under ''T. macrodentis''. They also could not determine how ''Tadzhikosuchus'' and the contemporaneous '' Zhyrasuchus'' were related, or even if they were synonyms, due to the poor fossils available. The name of ''Tadzhikosuchus'' is derived from the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Bissekty Formation
The Bissekty Formation (sometimes referred to as Bissekt) is a geologic formation and Lagerstätte which crops out in the Kyzyl Kum desert of Uzbekistan, and dates to the Late Cretaceous Period. Laid down in the mid to late Turonian, it is dated to about 92 to 90 Ma (million years ago). Description The lithology of the sediment largely consists of cross bedded sandstones with interbeds of massive sandstone, well cemented intraformational conglomerate, siltstones and mudstones. Most of the fossils are found as clasts within the conglomerates. Fossil content The Bissekty Formation is characterised by a mix of marine, brackish, freshwater, and terrestrial animal fossils. This stands in contrast the strictly marine fossils found in the underlying Dzheirantui Formation, and indicates that the Bissekty was formed during the regression of a saltwater sea. The coastline expanded inland again in the upper portion of the Bissekty, represented by a proportional increase of fully aqu ...

Zhyrasuchus
''Zhyrasuchus'' is an extinct monospecific genus of crocodylomorph that may have been a crocodylid eusuchian, but is only known from scanty material including a frontal (one of the bones of the roof of the skull). Its fossils were found in the Coniacian-age Upper Cretaceous Bissekty Formation of Dzharakhuduk, Uzbekistan. ''Zhyrasuchus'' was described in 1989 by Lev Nesov and colleagues. The type species is ''Z. angustifrons''. A 2000 review by Glenn Storrs and Mikhail Efimov could not determine how ''Zhyrasuchus'' and the contemporaneous ''Tadzhikosuchus ''Tadzhikosuchus'' is an extinct genus of neosuchian crocodyliform from the Late Cretaceous of Tajikistan.

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 necessaril ...

Fossils Of Uzbekistan
A fossil (from Classical Latin , ) is any preserved remains, impression, or trace of any once-living thing from a past geological age. Examples include bones, shells, exoskeletons, stone imprints of animals or microbes, objects preserved in amber, hair, petrified wood and DNA remnants. The totality of fossils is known as the ''fossil record''. Paleontology is the study of fossils: their age, method of formation, and evolutionary significance. Specimens are usually considered to be fossils if they are over 10,000 years old. The oldest fossils are around 3.48 billion years old to 4.1 billion years old. Early edition, published online before print. The observation in the 19th century that certain fossils were associated with certain rock strata led to the recognition of a geological timescale and the relative ages of different fossils. The development of radiometric dating techniques in the early 20th century allowed scientists to quantitatively measure the absolute ...

Turonian Life
The Turonian is, in the ICS' geologic timescale, the second age in the Late Cretaceous Epoch, or a stage in the Upper Cretaceous Series. It spans the time between 93.9 ± 0.8 Ma and 89.8 ± 1 Ma (million years ago). The Turonian is preceded by the Cenomanian Stage and underlies the Coniacian Stage. At the beginning of the Turonian an oceanic anoxic event (OAE 2) took place, also referred to as the Cenomanian-Turonian boundary event or the "Bonarelli Event". Stratigraphic definition The Turonian (French: ''Turonien'') was defined by the French paleontologist Alcide d'Orbigny (1802–1857) in 1842. Orbigny named it after the French city of Tours in the region of Touraine (department Indre-et-Loire), which is the original type locality. The base of the Turonian Stage is defined as the place where the ammonite species '' Watinoceras devonense'' first appears in the stratigraphic column. The official reference profile (the GSSP) for the base of the Turonian is located i ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Paralligatoridae
Paralligatoridae is an extinct family of neosuchian crocodyliforms that existed during the Jurassic and Cretaceous periods. It includes the genera ''Paralligator'', '' Brillanceausuchus'', '' Kansajsuchus'', ''Shamosuchus'', ''Scolomastax'', ''Sabresuchus'', '' Rugosuchus'', '' Batrachomimus'' and '' Wannchampsus'', as well as the yet-unnamed "Glen Rose form". Evolution Phylogenetic analyses of crocodyliforms find Paralligatoridae to nest within Neosuchia, a large clade (evolutionary grouping) that also includes modern crocodylians. In crocodyliform phylogeny, paralligatorids are usually found near the base of Neosuchia, outside the clade Eusuchia, which includes crocodylians and their closest relatives. Below is a cladogram A cladogram (from Greek ''clados'' "branch" and ''gramma'' "character") is a diagram used in cladistics to show relations among organisms.

Crocodyloid
Crocodyloidea is one of three superfamilies of crocodilians, the other two being Alligatoroidea and Gavialoidea, and it includes the crocodiles. Crocodyloidea may also include the extinct Mekosuchinae, native to Australasia from the Eocene to the Holocene, although this is disputed. Classification Cladistically, it is defined as ''Crocodylus niloticus'' (the Nile crocodile) and all crocodylians more closely related to ''C. niloticus'' than to either ''Alligator mississippiensis'' (the American alligator) or ''Gavialis gangeticus'' (the gharial). This is a stem-based definition for crocodiles, and is more inclusive than the crown group Crocodylidae. As a crown group, Crocodylidae only includes the last common ancestor of all extant (living) crocodiles and their descendants (living or extinct), whereas Crocodyloidea, as a stem group, also includes more basal extinct crocodile ancestors that are more closely related to living crocodiles than to alligators or gavialids.

Prodiplocynodon
''Prodiplocynodon'' is an extinct genus of basal crocodyloid crocodylian. It is one of the only crocodyloids known from the Cretaceous and existed during the Maastrichtian stage. The only species of ''Prodiplocynodon'' is the type species ''P. langi'' from the Lance Formation of Wyoming, known only from a single holotype skull lacking the lower jaw. The skull was collected by the American Museum Expedition of 1892 from exposures near the Cheyenne River in Niobrara County. It was described by Charles C. Mook of the American Museum of Natural History in 1941. The generic name means "before ''Diplocynodon''" because Mook saw close similarities between the holotype skull and that of the alligatoroid '' Diplocynodon'' from the Eocene of Europe. Description Most of the cranial sutures that outline individual bones of the skull are not visible in the holotype, and are often obscured by cracks. However, the overall shape of ''Prodiplocynodon'' is similar to that of basal all ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Dentary
In anatomy, the mandible, lower jaw or jawbone is the largest, strongest and lowest bone in the human facial skeleton. It forms the lower jaw and holds the lower teeth in place. The mandible sits beneath the maxilla. It is the only movable bone of the skull (discounting the ossicles of the middle ear). It is connected to the temporal bones by the temporomandibular joints. The bone is formed in the fetus from a fusion of the left and right mandibular prominences, and the point where these sides join, the mandibular symphysis, is still visible as a faint ridge in the midline. Like other symphyses in the body, this is a midline articulation where the bones are joined by fibrocartilage, but this articulation fuses together in early childhood.Illustrated Anatomy of the Head and Neck, Fehrenbach and Herring, Elsevier, 2012, p. 59 The word "mandible" derives from the Latin word ''mandibula'', "jawbone" (literally "one used for chewing"), from '' mandere'' "to chew" and ''-bula'' ( ...
