Lanthanosuchoid
Lanthanosuchoidea is an extinct superfamily of ankyramorph parareptiles from the middle Pennsylvanian to the middle Guadalupian epoch ( Moscovian - Wordian stages) of Europe, North America and Asia. It was named by the Russian paleontologist Ivachnenko in 1980, and it contains two families Acleistorhinidae and Lanthanosuchidae. Phylogeny Lanthanosuchoidea is a node-based taxon defined in 1997 as "the most recent common ancestor of ''Lanthanosuchus'', ''Lanthaniscus'', and ''Acleistorhinus''". The cladogram below follows the topology from a 2011 analysis by Ruta ''et al.'' The cladogram below follows the topology from a 2016 analysis by MacDougall ''et al.'' However, the phylogenetic analysis conducted by Cisneros ''et al.'' (2021) did not recover a clade uniting lanthanosuchids and acleistorhinids to the exclusion of all other parareptiles. Instead, acleistorhinids were recovered as the sister group of the clade Procolophonia, while lanthanosuchids were recovered withi ...

Feeserpeton
''Feeserpeton'' is an extinct genus of parareptile from the Early Permian of Richard's Spur, Oklahoma. It is known from a single species, ''Feeserpeton oklahomensis'', which was named in 2012 on the basis of a nearly complete skull. ''Feeserpeton'' is a member of the clade Lanthanosuchoidea and is one of the earliest parareptiles. Description The only known skull of ''Feeserpeton'' is small, but well-fused bones, deep pitting, and worn teeth indicate that the individual was close to maturity when it died. Large eye sockets may indicate that ''Feeserpeton'' was nocturnal. The skull is nearly complete, missing parts of the premaxilla (a bone at the tip of the snout) and the jugal (a bone making up the "cheek" region). A combination of features distinguish ''Feeserpeton'' from other related parareptiles, including a triangular skull, large caniniform teeth in the upper and lower jaws, and postorbital bones behind the eye sockets that are much larger than the nearby squamosal bone ...

Ankyramorph
Ankyramorpha ("anchor forms") is an extinct clade of procolophonomorph parareptiles which lived between the early Cisuralian epoch (middle Sakmarian stage) to the latest Triassic period (latest Rhaetian stage) of Africa, Antarctica, Asia, Australia, Europe, North America and South America.Jalil, N. E., & Janvier, P. (2005). Les pareiasaures (Amniota, Parareptilia) du Permien supérieur du Bassin d’Argana, Maroc. Geodiversitas, 27(1), 35-132. This clade was named in a 1996 parareptile study by Michael deBraga and Robert R. Reisz. They provided the name Ankyramorpha for a newly recognized clade encompassing "the most recent common ancestor of Procolophonia and Lanthanosuchoidea and all its descendants", and this clade name sees continued use among modern parareptile studies. A similar name, Hallucicrania, was provided in an earlier 1995 study by Michael S. Y. Lee, who defined it as the node-based taxon formed by the most recent common ancestor of lanthanosuchids and "parei ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Colobomycter
''Colobomycter'' is an extinct genus of lanthanosuchoid parareptile known from the Early Permian of Oklahoma. Discovery The type species, ''Colobomycter pholeter'', was first described from fossil remains in 1958, at which time it was believed to represent a synapsid, specifically, a pelycosaur. However, the discovery of new material and reexamination of the holotype led to its reclassification as a member of the Eureptilia. More recent studies indicate that ''Colobomycter'' is properly placed within the amniote clade Parareptilia, as part of the group Lanthanosuchoidea and closely related to the taxon '' Acleistorhinus''. A second species of ''Colobomycter'' was described in 2016, ''Colobomycter vaughni''. No postcranial material is known for ''Colobomycter'', and the skull material referred to the genus has all been recovered from a single locality, the Richards Spur site at the Dolese Brothers Limestone Quarry, 11 kilometers north of Fort Sill, Comanche County, Oklaho ...

Delorhynchus
''Delorhynchus'' is an extinct genus of lanthanosuchoid parareptile known from the late Early Permian (Artinskian age) Garber Formation of Comanche County, Oklahoma. It contains three species: the type species ''D. priscus'' is based on a series of maxillae. The second species to be described, ''D. cifellii'', is known from a larger number of well-preserved skulls and skeletal material. The third species, ''D. multidentatus'', is based on a fragmentary skull with several rows of teeth on its jaw. Discovery The type species, ''D. priscus,'' was first described and named by Richard C. Fox in 1962. The generic name "''Delorhynchus''" is derived from Greek ''rhynchos''/''ρυγχος'', meaning "beak" (a common suffix for extinct reptile genera names). The specific name of the type species ''D. priscus'' is derived from Greek ''πρίσκος'', meaning "ancient" or "venerable" in reference to the fragmentary nature of the known remains. ''D. priscus'' is known from the holot ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Acleistorhinidae
Acleistorhinidae is an extinct family of Late Carboniferous and Early Permian-aged ( Moscovian to Kungurian stage) parareptiles. Acleistorhinids are most diverse from the Richards Spur locality of the Early Permian of Oklahoma. Richards Spur acleistorhinids include '' Acleistorhinus'', '' Colobomycter'', and possibly '' Delorhynchus'' and '' Feeserpeton''. Other taxa include ''Carbonodraco'' from the Late Carboniferous of Ohio and '' Karutia'' from the Early Permian of Brazil. Acleistorhinidae is commonly considered a subgroup of lanthanosuchoids, related to taxa such as '' Chalcosaurus'', '' Lanthaniscus'' and '' Lanthanosuchus''. However, a re-examination of parareptile phylogeny conducted by Cisneros ''et al.'' (2021) argued that lanthanosuchids were not closely related to acleistorhinids. The phylogenetic analysis conducted by these authors recovered acleistorhinids as the sister group of the clade Procolophonia, while lanthanosuchids were recovered within the procolophon ...

Parareptile
Parareptilia ("at the side of reptiles") is a subclass or clade of basal sauropsids (reptiles), typically considered the sister taxon to Eureptilia (the group that likely contains all living reptiles and birds). Parareptiles first arose near the end of the Carboniferous period and achieved their highest diversity during the Permian period. Several ecological innovations were first accomplished by parareptiles among reptiles. These include the first reptiles to return to marine ecosystems (mesosaurs), the first bipedal reptiles ( bolosaurids such as ''Eudibamus''), the first reptiles with advanced hearing systems ( nycteroleterids and others), and the first large herbivorous reptiles (the pareiasaurs). The only parareptiles to survive into the Triassic period were the procolophonoids, a group of small generalists, omnivores, and herbivores. The largest family of procolophonoids, the procolophonids, rediversified in the Triassic, but subsequently declined and became extinct by the ...

Acleistorhinus
''Acleistorhinus'' (ah-kles-toe-RYE-nuss) is an extinct genus of parareptile known from the Early Permian (middle Kungurian stage) of Oklahoma. It is notable for being the earliest known anapsid reptile yet discovered. The morphology of the lower temporal fenestra of the skull of ''Acleistorhinus'' bears a superficial resemblance to that seen in early synapsids, a result of convergent evolution. Only a single species, ''A. pteroticus'', is known, and it is classified in the Family Acleistorhinidae, along with ''Colobomycter'' (also from the Early Permian of Oklahoma). Etymology ''Acleistorhinus'' was first discovered and named by Eleanor Daly in 1969 in the Hennessey Formation of South Grandfield, Tillman county, Oklahoma. The name ''Acleistorhinus'' combines Greek ''rhin'' (ῥῑ́ν), meaning "nose," and akleistos, Greek for “unclosed.“ Description and Paleobiology Skull Although its total body length is unknown, an ''Acleistorhinus'' skull is about 3.5 centimetres lo ...

Cladogram
A cladogram (from Greek ''clados'' "branch" and ''gramma'' "character") is a diagram used in cladistics to show relations among organisms. A cladogram is not, however, an evolutionary tree because it does not show how ancestors are related to descendants, nor does it show how much they have changed, so many differing evolutionary trees can be consistent with the same cladogram. A cladogram uses lines that branch off in different directions ending at a clade, a group of organisms with a last common ancestor. There are many shapes of cladograms but they all have lines that branch off from other lines. The lines can be traced back to where they branch off. These branching off points represent a hypothetical ancestor (not an actual entity) which can be inferred to exhibit the traits shared among the terminal taxa above it. This hypothetical ancestor might then provide clues about the order of evolution of various features, adaptation, and other evolutionary narratives about ance ...
