Diabloroter
''Diabloroter'' is a Carboniferous genus of brachystelechid ' microsaur' from the Mazon Creek The Mazon Creek fossil beds are a conservation ' found near Morris, in Grundy County, Illinois. The fossils are preserved in ironstone concretions, formed approximately in the mid- Pennsylvanian epoch of the Carboniferous period. These concreti ... lagerstätte in Illinois. It was named in 2019 by Arjan Mann and Hillary C. Maddin. History of study The genus name is derived from the roots ''diabolus'' ("devil"), which refers to the stark red color of the latex peels used in the original study, and ''rota'' ("wheel") to refer to the English rotavator (a digger), which in turn refers to the fossorial ecology of recumbirostrans. The specific name honors American paleontologist John Bolt. The taxon is represented by a single, nearly complete skeleton that was collected from the Sunspot Mine at Mazon Creek, Illinois.

Carrolla
''Carrolla'' is an extinct genus of brachystelechid 'microsaur' that lived in the Lower Permian in North America. It was named in 1986 by American paleontologists Wann Langston and Everett Olson. The type species, ''Carrolla craddocki'', is the only known species. History of study ''Carrolla'' was named for the type species by Langston & Olson (1986) for a single, complete skull collected from the early Permian of Archer County, Texas; the specimen is reposited at the Texas Memorial Museum in Austin. They immediately recognized the similarity to Brachystelechus'',' the eponymous genus from Europe; this genus was subsequently synonymized with ''Batropetes,'' traditionally considered a reptile but which had taxonomic precedent. Numerous features were cited as evidence for an ability to burrow, which was considered rare among 'microsaurs' at the time, and several shared features with modern amphibians were noted, although some of these have been subsequently disproven.

Recumbirostra
Recumbirostra is a clade of tetrapods which lived during the Carboniferous and Permian periods. They are thought to have had a fossorial (burrowing) lifestyle and the group includes both short-bodied and long-bodied snake-like forms. At least one species, the molgophid ''Nagini mazonense,'' lost its forelimbs entirely. It includes the families Pantylidae, Gymnarthridae, Ostodolepidae, Rhynchonkidae and Brachystelechidae, with additional families such as Microbrachidae and Molgophidae being included by some authors. Recumbirostra was erected as a clade in 2007 to include many of the taxa traditionally grouped in "Microsauria", which has since been shown to be a paraphyletic or polyphyletic grouping. Like other "microsaurs", the recumbirostrans have traditionally been considered to be members of the subclass Lepospondyli; however, many phylogenetic analyses conducted since the 2010s have recovered recumbirostrans as basal sauropsid amniotes instead. Not all phylogenetic analyses rec ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Carboniferous
The Carboniferous ( ) is a geologic period and system of the Paleozoic that spans 60 million years from the end of the Devonian Period million years ago ( Mya), to the beginning of the Permian Period, million years ago. The name ''Carboniferous'' means "coal-bearing", from the Latin '' carbō'' ("coal") and '' ferō'' ("bear, carry"), and refers to the many coal beds formed globally during that time. The first of the modern 'system' names, it was coined by geologists William Conybeare and William Phillips in 1822, based on a study of the British rock succession. The Carboniferous is often treated in North America as two geological periods, the earlier Mississippian and the later Pennsylvanian. Terrestrial animal life was well established by the Carboniferous Period. Tetrapods (four limbed vertebrates), which had originated from lobe-finned fish during the preceding Devonian, became pentadactylous in and diversified during the Carboniferous, including early amphibian line ...

Batropetes
''Batropetes'' is an extinct genus of Brachystelechidae, brachystelechid recumbirostran "Microsauria, microsaur". ''Batropetes'' lived during the Sakmarian stage of the Early Permian. Fossils attributable to the type species ''B. fritschi'' have been collected from the town of Freital in Saxony, Germany, near the city of Dresden. Additional material has been found from the Saar-Nahe Basin in southwestern Germany and has been assigned to three additional species: ''B. niederkirchensis'', ''B. palatinus'', and ''B. appelensis''. Description ''Batropetes'' is small and short-bodied for a microsaur. Its average total body length was about . The Orbit (anatomy), orbits are large and the skull is short. ''Batropetes'' possesses scales on its underside that are similar to those of reptiles. ''Batropetes'' is distinguished from ''Carrolla'', another brachystelechid microsaur, by the presence of three cusps on the premaxillary and anterior dentary teeth. In ''Carrolla'', there are only ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Quasicaecilia
''Quasicaecilia'' is an extinct genus of microsaur. It is known from the Early Permian of Texas in the United States. A single specimen is known, collected from the Texas Permian redbeds by Charles Hazelius Sternberg in 1917. It was originally identified as a specimen of the gymnarthrid microsaur ''Cardiocephalus''. The skull is small, less than in length, and the otic capsule (a hollow region of bone encapsulating the inner ear) is very large in comparison to the rest of the skull. The skull of ''Quasicaecilia'' superficially resembles those of extant but unrelated caecilians, hence the genus name. ''Quasicaecilia'' was assigned to the new family Brachystelechidae in 1991 along with the genera ''Batropetes'' and ''Carrolla''.
