Rhinesuchus is a large temnospondyl. Remains of the genus are known from the Permian of the South African Karoo Basin's Tapinocephalus and Cistecephalus assemblage zones, both belonging to the Beaufort Group. The skull of Rhinesuchus had a flat triangular shape with blunt snout similar to some of the other large temnospondyls, and had a palate filled with small sharp teeth, suggesting that it hunted fish. Also, the small eyes were on top of the head suggesting that it approached its prey from below.
Aphaneramma is an extinct genus of marine temnospondyl amphibian. It lived during the Early Triassic epoch, approximately 252–247 Ma ago, and had a global distribution.
The Stereospondyli are a group of extinct temnospondyl amphibians that existed primarily during the Mesozoic period. They are known from all seven continents and were common components of many Triassic ecosystems, likely filling a similar ecological niche to modern crocodilians prior to the diversification of pseudosuchian archosaurs.
Wetlugasaurus is an extinct genus of temnospondyl from the Early Triassic (Olenekian) Charkabozh, Kzylsaiskaya, Petropavlovka, Kamennyi Yar and Vetluga Series Formations of northern Russia and Greenland. It had a 22 centimetres (8.7 in) long skull, and reached a total length of 1 metre.
Eryosuchus is an extinct genus of capitosauroid temnospondyl from the Middle Triassic of northern Russia. It was a very large predator: the largest specimen known could reach up to 3.5 m (11.5 ft) in length, with a skull over 1 m long.
Trematosaurus is an extinct genus of trematosaurid temnospondyl amphibian found in Germany and Russia. It was first named by Hermann Burmeister in 1849 and the type species is Trematosaurus brauni.
Eocyclotosaurus is an extinct genus of mastodonsauroid temnospondyl from the Middle Triassic (Anisian). The name Eocyclotosaurus means "dawn round-eared lizard". It is characterized as a capitosauroid with a long and slender snout, closed otic fenestra, and small orbits. It measured over one metre and had a 22 cm skull.
Benthosuchus is an extinct genus of temnospondyl amphibian from the Early Triassic of Russia. It was primarily aquatic, living in rivers and lakes. Multiple species are known, with the largest reaching about 2.5 meters in length.
Lydekkerinidae is a family of stereospondyl temnospondyls that lived in the Early Triassic period. During this time period, lydekkerinids were widely distributed, with putative remains reported from Russia, Greenland, India, South Africa, Madagascar, Australia, and Antarctica. In contrast to most other stereospondyls, lydekkerinids were relatively small-bodied. The type genus is Lydekkerina, the namesake of the family and the best-known lydekkerinid.
Cosgriffius is an extinct genus of trematosaurian temnospondyl within the family Trematosauridae. It was described in 1993 by Samuel P. Welles based on a single partial skull from the well-known Meteor Crater Quarry in Arizona that also produced more abundant remains of the capitosaur Wellesaurus peabodyi. The skull was long and slender, features typically associated with the trematosaurid subfamily Lonchorhynchinae. This is the only trematosaurid known from western North America.
Odenwaldia is an extinct genus of mastodonsauroid temnospondyl within the family Heylerosauridae.
Capitosauria is an extinct group of large temnospondyl amphibians with simplified stereospondyl vertebrae. Mainly living as piscivores in lakes and rivers, the Capitosauria and its sister taxon Trematosauria were the only major labyrinthodonts that existed during the Mesozoic in ecological niches broadly similar to those of modern crocodiles, and some grew to very large sizes. At 6 meters in length, the Mid-Triassic Mastodonsaurus giganteus is not only thought to have been the largest capitosaur, but possibly also the largest amphibian to have lived. The latest known remains are from the Rhaetian of Germany and are referred to Cyclotosaurus.
Paleontology or palaeontology is the study of prehistoric life forms on Earth through the examination of plant and animal fossils. This includes the study of body fossils, tracks (ichnites), burrows, cast-off parts, fossilised feces (coprolites), palynomorphs and chemical residues. Because humans have encountered fossils for millennia, paleontology has a long history both before and after becoming formalized as a science. This article records significant discoveries and events related to paleontology that occurred or were published in the year 2011.
Calmasuchus is a genus of capitosaurian temnospondyl which lived during the middle Triassic. Fossils of Calmasuchus have been recovered from the La Mora site of the Catalan basin in Barcelona of Spain. Identified from a partial skull roof and palate, skull fragments and complete hemi-mandible, it was named by Josep Fortuny, Àngel Galobart and Carles De Santisteban in 2011. The type species is Calmasuchus acri.
Vladlenosaurus is an extinct genus of capitosaurian temnospondyl from Russia. It lived during the late Vetlugian. Based on the type of deposits it was found in, Vladlenosaurus probably inhabited lacustrine, or lake, habitats. The type species is V. alexeyevi, named in 2000.
Stenotosauridae is an extinct family of mastodonsauroid temnospondyls. It has included genera such as Stenotosaurus, Wellesaurus, and Procyclotosaurus.
Heylerosauridae is a family of mastodonsauroid temnospondyls. It was first named in 1980 to include the genera Odenwaldia and Quasicyclotosaurus. In addition to these genera, the family now includes Eocyclotosaurus and Yuanansuchus. Recent phylogenetic analyses have not found a close relationship between Odenwaldia and other heylerosaurids and place it outside the family. Heylerosaurids are generally regarded as the sister taxon of the stenotosaurids.
Tatrasuchus is an extinct genus of temnospondyl from the Middle Triassic of Poland. It is classified as a member of the family Cyclotosauridae or Mastodonsauridae. It is closely related to the genus Cyclotosaurus. The type species, Tatrasuchus kulczyckii, was named in 1996. Damiani (2001) considered genus Kupferzellia Schoch (1997) from Middle Triassic of Germany to be a junior synonym of Tatrasuchus, and recombined its type species, K. wildi as the second species of Tatrasuchus. This classification was followed by some authors, e.g. Fortuny et al. (2011); other authors, e.g. Schoch (2008), maintain Tatrasuchus and Kupferzellia as distinct genera.
Warrenisuchus is an extinct genus of temnospondyl from the Early Triassic of Queensland, Australia. It belongs to a diverse group of Triassic temnospondyls called Capitosauria. The type species Warrenisuchus aliciae was erected in 2009. W. aliciae was originally described as a species of Parotosuchus in 1988, which is known from other species that have been found in Europe, Africa, and Antarctica. In 2000 it was then assigned to a new genus called Rewanobatrachus along with the newly named species R. gunganj, which was declared the type species of the genus. However, R. gunganj was later reclassified as a species of Watsonisuchus, invalidating the name Rewanobatrachus and requiring that R. aliciae be placed in its own genus, which was named Warrenisuchus. However, several studies suggest that Warrenisuchus aliciae may be a species of Watsonisuchus as well. Unlike most capitosaurs, Warrenisuchus is known from many juvenile skulls less than 4 centimetres (1.6 in) in length.
