Paleorhinus is an extinct genus of widespread basal phytosaur known from the Late Triassic. The genus was named in 1904 based on the type species Paleorhinus bransoni, which is known from Wyoming and Texas in the United States. Another valid species, Paleorhinus angustifrons from Bavaria, Germany, is also commonly referred to the genus. Paleorhinus had a length of about 2.5 meters.
Metoposaurus meaning "front lizard" is an extinct genus of stereospondyl temnospondyls, known from the Late Triassic of Germany, Italy, Poland, and Portugal. This mostly aquatic animal possessed small, weak limbs, sharp teeth, and a large, flat head. This highly flattened creature mainly fed on fish, which it captured with its wide jaws lined with needle-like teeth. Many Metoposaurus mass graves have been found, probably from creatures that grouped together in drying pools during drought.
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.
Metoposauroidea is an extinct superfamily of temnospondyls that lived from the Middle to Upper Triassic in North America, Europe and North Africa. Metoposauroidea includes the families Metoposauridae and Latiscopidae.
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.
Cherninia is an extinct genus of mastodonsaurid temnospondyl. The type species, Cherninia denwai, is known from the Denwa Formation of India. It is based on a massive skull, ISI A 54, which was originally considered a species of Parotosuchus in 1998 before being given its own genus in 2001.
Apachesaurus is an extinct genus of metoposaurid temnospondyls from western North America.
Metoposauridae is an extinct family of trematosaurian temnospondyls. The family is known from the Triassic period. Most members are large, approximately 1.5 metres (4.9 ft) long and could reach 3 m long. Metoposaurids can be distinguished from the very similar mastodonsauroids by the position of their eyes, placed far forward on the snout.
Eupelor is a dubious genus of prehistoric amphibian belonging to the temnospondyl family Metoposauridae. Fossils have been found in present-day Pennsylvania, within the Newark Supergroup, dating to the Late Triassic (Norian).
Arganasaurus is an extinct genus of temnospondyls belonging to the family Metoposauridae that lived in Morocco during the Late Triassic (Carnian).
Almasaurus is an extinct genus of trematosaurian temnospondyl within the family Latiscopidae. It is known from several skulls and some postcranial material found from the Argana Formation in Morocco, which dates back to the Late Triassic.
Dutuitosaurus is a genus of metoposaurids, a group of temnospondyls that lived during the Late Triassic period. Dutuitosaurus was discovered in the early 1960s in Morocco and is known from the lower t5 units of the Timezgadiouine Formation exposures in the Argana Basin of the High Atlas Mountains and was first described in 1976 by French paleontologist Jean-Michel Dutuit. Material of Dutuitosaurus is currently held in the Muséum national d'histoire naturelle (MNHN) in Paris, France. It was originally placed within Metoposaurus as M. ouazzoui but was subsequently placed in its own genus, Dutuitosaurus, by Hunt (1993), who identified a number of differences between Metoposaurus and the Moroccan metoposaurids. Features that differentiate Dutuitosaurus from other metoposaurids include relative elongate intercentra and a maxilla that enters the orbit.
Dictyocephalus is an extinct genus of prehistoric temnospondyls; the only species is Dictyocephalus elegans. This taxon was one of the first metoposaurids to be discovered in North America, being discovered by Ebeneezer Emmons and briefly described by Joseph Leidy in 1856 in the Newark supergroup exposures of Chatham County, North Carolina. At the time, Leidy was uncertain of much of the anatomy of D. elegans, which is represented only by a small partial skull and made only brief descriptions and measurements of a few elements, with an estimated size based on the long-snouted trematosaur Trematosaurus. Emmons provided the first figures of the specimen the following year. Romer (1947) briefly mentioned that the specimen was indistinguishable from "Buettneria" (Koskinonodon).
Rileymillerus is an extinct genus of temnospondyl amphibian from the Late Triassic Post Quarry in the Dockum Group of Texas that was described by John Bolt and Sankar Chatterjee in 2000. The holotype, a nearly complete skull with articulated jaws, is housed at the Museum of Texas Tech University. The genus is named for Riley Miller, who allowed Chatterjee to work on the Post Quarry, and the species is named for the paleontologist John Cosgriff.
Anaschisma is an extinct genus of large temnospondyls. These animals were part of the family called Metoposauridae, which filled the crocodile-like predatory niches in the late Triassic. It had large skull about 62 centimetres (24 in) long, and possibly reached 3 metres (9.8 ft) long. It was an ambush hunter, snapping up anything small enough to fit in its huge jaws. It was very common during the Late Triassic in what is now the American Southwest.
The Popo Agie Formation is a Triassic geologic formation that crops out in western Wyoming, western Colorado, and Utah. It was deposited during the Late Triassic in fluvial (river) and lacustrine (lake) environments that existed across much of what is now the American southwest. Fragmentary fossils of prehistoric reptiles and amphibians, including pseudosuchian reptiles and temnospondyl amphibians, have been discovered in the Popo Agie Formation. Dinosaur remains are also among the fossils that have been recovered from the formation, although none have yet been referred to a specific genus.
The Upper Maleri Formation is a sedimentary rock formation found in Telangana, India. It is one of the formations of the Pranhita–Godavari Basin. It is of late Norian and possibly earliest Rhaetian ages, and is notable for its fossils of early dinosaurs.
Sanjukta Chakravorti is a geologist and palaeobiologist. She completed her PhD from the Geological Studies Unit, Indian Statistical Institute Kolkata, India where she is an Honorary Visiting Scientist. Her research focuses on Gondwanan Geology and Triassic temnospondyl amphibians from India. She also actively works on palaeoecology and palaeobiology of marine vertebrates in India. Sanjukta currently conducts her research at the State Museum of Natural History Stuttgart.
Buettnererpeton is an extinct genus of large temnospondyls known from the Late Triassic Dockum Group in Texas. The type species, B. bakeri, was long classified as part of other genera, such as Metoposaurus and Koskinonodon, but was placed in its own genus in 2022.
