Kansajsuchus
''Kansajsuchus'' is an extinct genus of paralligatorid mesoeucrocodylian. It is based on PIN 2399/301, a right premaxilla, one of the bones of the tip of the snout. This specimen was found in rocks of the lower Santonian-age Upper Cretaceous Yalovach Svita of Kansai, in the Fergana Basin of Tajikistan. Additional fossils including vertebrae and bony armor have been assigned to this genus. It would have been a large animal, estimated at up to long. ''Kansajsuchus'' was described in 1975 by Mikhail Efimov. The type species is ''Kansajsuchus extensus''. Halliday ''et al.'' (2013) confirmed the validity of the species ''K. extensus'', and its phylogenetic position among other basal goniopholidids from Asia. '' "Sunosuchus" shartegensis'' was found to represent its sister taxon, and both species were placed in a distinct lineage from the type species of ''Sunosuchus'', '' S. miaoi'', however with a weak support. Therefore, the authors raised the suggestion that later revi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Paralligatorid
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.

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 aquat ...

Sunosuchus Shartegensis
''Chalawan'' (from th, ชาละวัน ) is an extinct genus of pholidosaurid mesoeucrocodylian known from the Late Jurassic or Early Cretaceous Phu Kradung Formation of Nong Bua Lamphu Province, northeastern Thailand. It contains a single species, ''Chalawan thailandicus'', with ''Chalawan shartegensis'' as a possible second species. Discovery and Naming The first fossil of ''Chalawan'' was a nearly complete lower jaw collected in the early 1980s from a road-cut near the town of Nong Bua Lamphu, in the upper part of the Phu Kradung Formation. This mandible was at first known from the posterior portion of the bone, described and named by Eric Buffetaut and Rucha Ingavat in 1980 as a new species of the goniopholidid ''Sunosuchus'', ''Sunosuchus thailandicus''. Shortly afterwards more material of the same specimen was found and described. In the early 2000s another locality of the Phu Kradung Formation was discovered near the village of Kham Phok, Mukdahan Province, yieldi ...

Late Cretaceous
The Late Cretaceous (100.5–66 Ma) is the younger of two epochs into which the Cretaceous Period is divided in the geologic time scale. Rock strata from this epoch form the Upper Cretaceous Series. The Cretaceous is named after ''creta'', the Latin word for the white limestone known as chalk. The chalk of northern France and the white cliffs of south-eastern England date from the Cretaceous Period. Climate During the Late Cretaceous, the climate was warmer than present, although throughout the period a cooling trend is evident. The tropics became restricted to equatorial regions and northern latitudes experienced markedly more seasonal climatic conditions. Geography Due to plate tectonics, the Americas were gradually moving westward, causing the Atlantic Ocean to expand. The Western Interior Seaway divided North America into eastern and western halves; Appalachia and Laramidia. India maintained a northward course towards Asia. In the Southern Hemisphere, Australia and Ant ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Type Species
In zoological nomenclature, a type species (''species typica'') is the species name with which the name of a genus or subgenus is considered to be permanently taxonomically associated, i.e., the species that contains the biological type specimen(s). Article 67.1 A similar concept is used for suprageneric groups and called a type genus. In botanical nomenclature, these terms have no formal standing under the code of nomenclature, but are sometimes borrowed from zoological nomenclature. In botany, the type of a genus name is a specimen (or, rarely, an illustration) which is also the type of a species name. The species name that has that type can also be referred to as the type of the genus name. Names of genus and family ranks, the various subdivisions of those ranks, and some higher-rank names based on genus names, have such types.

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 abso ...

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 in the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Sunosuchus Miaoi
''Sunosuchus'' is an extinct genus of goniopholidid mesoeucrocodylian. Fossils are known from China, Kyrgyzstan, and Thailand and are Jurassic in age, although some may be Early Cretaceous. Four species are currently assigned to the genus: the type species ''S. miaoi'' and the species ''S. junggarensis'', ''S. shartegensis'', and ''S. shunanensis''. All species are from China. ''Goniopholis phuwiangensis'', also from Thailand, was reassigned to ''Sunosuchus'' by Andrade ''et al.'' (2011). The material from Kyrgyzstan has not been assigned to any species. Description ''Sunosuchus'' has a long, narrow snout and a small skull table. Several characters help diagnose ''Sunosuchus'' and distinguish it from other taxa. For example, there are wide pits on the back of the frontal bone. The frontal bone also has a distinctive ridge along part of its midline. The lower jaw has a long symphysis where the two halves come together. This symphysis is formed mostly from the mandibles, but also par ...
