Kapes Bentoni
''Kapes'' is an extinct genus of procolophonid parareptile from the Lower and Middle Triassic of the United Kingdom and Russia. It is a member of the subfamily Procolophoninae. The type species ''K. amaenus'' was named in 1975 from the banks of the Vychegda River in the Komi Republic of Russia. In 1983, a new species was brought into the genus, ''K. majmesculae''. ''K. majmesculae'' was first named in 1968 as a member of the genus ''Tichvinskia''. A third Russian species, ''K. serotinus'', was named in 1991. In 2002, ''Kapes bentoni'' was named from the Middle Triassic Otter Sandstone Formation of Devon, England, extending the geographic range of ''Kapes''. In the same paper, ''K. serotinus'' was synonymized with ''K. majmesculae'' and another Russian species was assigned to ''Kapes'' called ''K. komiensis''. ''K. komiensis'' was first named in 1975 (in the same paper ''K. amaenus'' was named in) as a member of the genus '' Macrophon''. Phylogeny Below is a cladogram A clado ...

Lower Triassic
The Early Triassic is the first of three epochs of the Triassic Period of the geologic timescale. It spans the time between Ma and Ma (million years ago). Rocks from this epoch are collectively known as the Lower Triassic Series, which is a unit in chronostratigraphy. The Early Triassic is the oldest epoch of the Mesozoic Era. It is preceded by the Lopingian Epoch (late Permian, Paleozoic Era) and followed by the Middle Triassic Epoch. The Early Triassic is divided into the Induan and Olenekian ages. The Induan is subdivided into the Griesbachian and Dienerian subages and the Olenekian is subdivided into the Smithian and Spathian subages. The Lower Triassic series is coeval with the Scythian Stage, which is today not included in the official timescales but can be found in older literature. In Europe, most of the Lower Triassic is composed of Buntsandstein, a lithostratigraphic unit of continental red beds. The Early Triassic and partly also the Middle Triassic span the int ...

Procolophonidae
Procolophonidae is an extinct family of small, lizard-like parareptiles known from the Late Permian to Late Triassic that were distributed across Pangaea, having been reported from Europe, North America, China, South Africa, South America, Antarctica and Australia. The most primitive procolophonids were likely insectiovous or omnivorous, more derived members of the clade developed bicusped molars, and were likely herbivorous feeding on high fiber vegetation or durophagous omnivores. Many members of the group are noted for spines projecting from the quadratojugal bone of the skull, which likely served a defensive purpose as well as possibly also for display. At least some taxa were likely fossorial burrowers. While diverse during the Early and Middle Triassic, they had very low diversity during the Late Triassic, and were extinct by the beginning of the Jurassic.

Theledectes Perforatus
''Theledectes'' is an extinct genus of theledectine procolophonid parareptile from middle Triassic (early Anisian stage) deposits of Free State Province, South Africa.The type species, ''Theledectes perforatus'', is based on the holotype BP/1/4585, a flattened skull. This skull was collected by the South African palaeontologist, James W. Kitching from Hugoskop in the Rouxville District and referred to subzone B of the Cynognathus Assemblage Zone of the Burgersdorp Formation, Beaufort Group (Karoo Basin). The genus was first named by Sean P. Modesto and Ross J. Damiani in 2003. However, the species was initially assigned to the genus '' Thelegnathus'' (now considered to be a ''nomen dubium'') by C.E. Gow in 1977, as the species ''Thelegnathus perforatus''. Description Most of the skull is poorly preserved, with the exception of the tooth-bearing elements. ''Theledectes'' is the only known parareptile with more than one row of marginal teeth (teeth along the edge of the mout ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

''Eumetabolodon'' is an extinct genus of procolophonine procolophonid parareptile from early and middle Triassic (Induan to earliest Anisian stages) deposits of Nei Mongol, northern China.

Theledectinae
Theledectinae is an extinct subfamily of parareptiles within the family Procolophonidae. Theledectines existed in South Africa, China and Australia during the Early-Middle Triassic period (Induan to Anisian stages). Theledectinae was named by Juan Carlos Cisneros in 2008 to include the genus ''Theledectes'', and the species '' "Eumetabolodon" dongshengensis''. ''"E." dongshengensis'' represents a new genus from China. Cladistically, it is defined as "All taxa more closely related to ''Theledectes perforatus'' (Gow, 1977a) than to ''Procolophon trigoniceps ''Procolophon'' is a genus of lizard-like procolophonid parareptiles that first appeared in the Early Triassic (Induan) of South Africa, Brazil, and Antarctica.

Kitchingnathus Untabeni
''Kitchingnathus'' (Kitchings' mandible) is an extinct genus of basal procolophonid parareptile from Early Triassic (early Olenekian stage) deposits of Eastern Cape Province, South Africa. It is known from the holotype BP/1/1187, skull and partial postcranium, which was first assigned to the more derived ''Procolophon trigoniceps''. It was collected by the South African palaeontologist, James W. Kitching in October 1952 from Hobbs Hill, west of Cathcart.
