Libognathus
''Libognathus'' (meaning "southwest jaw" in Greek) is an extinct genus of procolophonid parareptile from the Late Triassic of Texas. The type and only species, ''Libognathus sheddi'', was named in 1997 from the Cooper Canyon Formation in the fossil-rich Post Quarry, which is found in Garza County. ''Libognathus'' was the first definite procolophonid discovered in the southwestern United States, although another possible procolophonid called '' Chinleogomphius'' was reported from the southwest before ''Libognathus'' was named. Description ''Libognathus'' is known from a single holotype specimen including the left dentary bone and coronoid process of the lower jaw, as well as six teeth implanted in the jaw. ''Libognathus'' can be identified as a procolophonid by its wide molar-like teeth, each of which has a ridge running along its width and several projections or cusps around it. It is considered a member of the procolophonid subfamily Leptopleuroninae based on the presence of m ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Koiloskiosaurus
''Koiloskiosaurus'' is an extinct genus of procolophonid parareptile from the Early Triassic of Germany. The type and only species ''Koiloskiosaurus coburgensis'' was named by German paleontologist Friedrich von Huene in 1911 from a layer of rocks called the Buntsandstein The Buntsandstein (German for ''coloured'' or ''colourful sandstone'') or Bunter sandstone is a lithostratigraphic and allostratigraphic unit (a sequence of rock strata) in the subsurface of large parts of west and central Europe. The Buntsandst .... ''Koiloskiosaurus coburgensis'' is known from a block of three fossilized skeletons preserved together. Given that the skeletons are oriented in the same direction, the individuals most likely died in a burrow. Features of the skeletons of ''Koiloskiosaurus'' and other procolophonids, such as robust limbs and solid, immovable skull bones, are also taken as evidence that they were burrowers.

Neoprocolophon
''Neoprocolophon'' is an extinct genus of procolophonid parareptile, known from the single species ''Neoprocolophon asiaticus'' from the Middle Triassic of China. It was named by Chinese paleontologist Yang Zhongjian (better known as C. C. Young) in 1957 from the Ermaying Formation The Ermaying Formation is a sedimentary succession of Anisian (Middle Triassic) age. It is found in the Shaanxi Province of China.

Phonodus
''Phonodus'' is an extinct genus of procolophonid parareptile. It is known from a single skull found from the Early Triassic Katberg Formation in South Africa. It is the oldest known member of the subfamily Leptopleuroninae, and was likely the result of a procolophonid migration into the Karoo Basin from Laurasia after the Permo-Triassic extinction event. Because ''Phonodus'' had large maxilla The maxilla (plural: ''maxillae'' ) in vertebrates is the upper fixed (not fixed in Neopterygii) bone of the jaw formed from the fusion of two maxillary bones.

Hypsognathus
''Hypsognathus'' (from el, ῠ̔́ψος , 'height' and el, γνάθος , 'jaw') is an extinct genus of procolophonid parareptile from the Late Triassic of New Jersey, Connecticut, and Nova Scotia.Sues, H.-D.,Olsen, P.E., Scott,D.M, and Spencer, P.S.

Leptopleuron
''Leptopleuron'' is an extinct genus of procolophonid that lived in the dry lands during the late Triassic in Elgin of northern Scotland and was the first to be included in the clade of Procolophonidae. First described by English paleontologist and biologist Sir Richard Owen, ''Leptopleuron'' is derived from two Greek bases, ''leptos'' for "slender" and ''pleuron'' for "rib," describing it as having slender ribs. The fossil is also known by a second name, ''Telerpeton'', which is derived from the Greek bases ''tele'' for "far off" and ''herpeton'' for "reptile." In Scotland, ''Leptopleuron'' was found specifically in the Lossiemouth Sandstone Formation. The yellow sandstone it was located in was poorly lithified with wind coming from the southwest. The environment is also described to consist of barchan dunes due to the winds, ranging up to 20 m tall that spread during dry phases into flood plains. Procolophonoids such as ''Leptopleuron'' were considered an essential addition to ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Soturnia
''Soturnia'' is an extinct genus of procolophonid parareptile. It is known from rocks of the Late Triassic-age Caturrita Formation of the municipality of Faxinal do Soturno in the geopark of Paleorrota, Brazil. ''Soturnia'' was named in 2003 by Cisneros and Schultz; the type species is ''S. caliodon''. It was a leptopleuroninae procolophonid.Cisneros, J.C.; and Schultz, C.L. (2003).

Sclerosaurus
''Sclerosaurus'' is an extinct genus of procolophonid parareptile known from the Early to Middle Triassic of Germany and Switzerland. It contains a single species, ''Sclerosaurus armatus''. It was fairly small about 30 cm long, distinguished from other known parareptiles by the possession of long, backwardly projecting spikes, rear lower jaw teeth with slightly imbricating crowns, and a narrow band of back armor comprising two or three rows of sculptured osteoderms on either side of the midline. Traditional classifications, e.g. Carroll (1988) placed ''Sclerosaurus'' with the procolophonids, however some phylogenetic studies have found it to be a close relative of the pareiasaurs, and together with that group it forms the clade Pareiasauroidea.Jalil, N. E., & Janvier, P. (2005). Les pareiasaures (Amniota, Parareptilia) du Permien supérieur du Bassin d’Argana, Maroc. Geodiversitas, 27(1), 35-132.

Triassic Parareptiles
The Triassic ( ) is a geologic period and system which spans 50.6 million years from the end of the Permian Period 251.902 million years ago ( Mya), to the beginning of the Jurassic Period 201.36 Mya. The Triassic is the first and shortest period of the Mesozoic Era. Both the start and end of the period are marked by major extinction events. The Triassic Period is subdivided into three epochs: Early Triassic, Middle Triassic and Late Triassic. The Triassic began in the wake of the Permian–Triassic extinction event, which left the Earth's biosphere impoverished; it was well into the middle of the Triassic before life recovered its former diversity. Three categories of organisms can be distinguished in the Triassic record: survivors from the extinction event, new groups that flourished briefly, and other new groups that went on to dominate the Mesozoic Era. Reptiles, especially archosaurs, were the chief terrestrial vertebrates during this time. A specialized subgroup of archosaur ...
