36 Triassic animal stubs

Adelobasileus is a genus of mammal-like cynodont from the Late Triassic (Carnian), about 225 million years ago. It is known only from a partial skull recovered from the Tecovas formation in western Texas, southern United States, referred to the species Adelobasileus cromptoni.

Andescynodon is a genus of traversodontid cynodonts from the Middle Triassic of Argentina. Fossils are known from the Cerro de las Cabras and Cacheutá Formations. Andescynodon is one of the most basal traversodontids. Another traversodontid called Rusconiodon has also been identified from the Cerro de las Cabras Formation but is now considered a junior synonym of Andescynodon.

Antrimpos is an extinct genus of crustacean which existed during the Triassic and Jurassic periods. It contains 15 species, including Antrimpos speciosus.

Aphaneramma is an extinct genus of temnospondyl amphibian. It lived during the Early Triassic epoch. Fossils have been found in the Mianwali Formation of Pakistan, Madagascar, the Zhitkov Formation of Russia, and the Kongressfjellet Formation of Svalbard (Norway). Aphaneramma grew up to 2 metres (6.6 ft) long, with a 23 centimetres (9.1 in) skull. Aphaneramma's jaws were very long, similar to the gharial's, and lined with small teeth. This adaptation suggests it may have preyed on fish. A marine lifestyle for this animal was proposed. Aphaneramma is closely related to Cosgriffius from North America,

Araxoceratidae is an extinct family of ceratitid ammonites, cephalopods that were found throughout the world. They arose during the Permian and died out during the early Triassic. The species of the type genus Araxoceras are used as markers for various Permian epochs.

Austrolimulus fletcheri is an extinct xiphosuran, related to the modern horseshoe crab. The holotype and only known specimen is from Middle Triassic-aged strata of Brookvale, New South Wales of Australia.

Aviculopecten is an extinct genus of bivalve mollusc that lived from the Early Devonian to the Late Triassic in Asia, Australia, Europe, North America, and South America.

Axitectum is an extinct genus of bystrowianid reptiliomorph from lower Triassic deposits of Nizhni Novgorod and Kirov Regions, Russia. It was a rather large animal judging by the size of its vertebrae. The back was covered in bands of highly ornamented osteoderm plates, similar to those found in modern crocodiles. The bands overlapped with the next band at the posterior end.

Batrachosuchus is a genus of temnospondyl amphibian that existed from the Early to Middle Triassic of Southern Africa and the Blina Shale of Australia.

Boreopelta is an extinct genus of rhytidosteid temnospondyl from the early Triassic period of Yakutsk Region, central Siberia, Russia. It is known from the holotype PIN 4115/1, a skull fragment and from the referred specimen PIN 4113/5, a partial lower jaw, recovered from the Teryutekhskaya Formation near the Karya-khos-Teryutekh River. This genus was named by M. A. Shishkin and M. N. Vavilov in 1985, and the type species is Boreopelta vavilovi.

Brachyopomorpha is a clade of stereospondyl temnospondyls within the infraorder Trematosauria. It was constructed in 2000 to include Bothriceps australis and the superfamily Brachyopoidea. It is phylogenetically defined as a stem-based taxon including Pelorocephalus and all taxa closer to it than to Rhytidosteus. In contrast, Brachyopoidea is defined as a node-based taxon including Brachyops and Pelorocephalus and all descendants of their most recent common ancestor. Because Bothriceps is not thought to be a descendant of that recent common ancestor and would be more basal than it, the genus is placed just outside Brachyopoidea and is considered to be a sister taxon to the clade.

Bystrowiella is an extinct genus of bystrowianid reptiliomorph from upper Middle Triassic deposits of Kupferzell and Vellberg, northern Baden-Württemberg, Germany. It was first named by Florian Witzmann, Rainer R. Schoch and Michael W. Maisch in 2008, from a complete osteoderm fused with tip of neural spine, partial osteoderms and vertebrae. The type species is Bystrowiella schumanni. The genus is named in honour of Dr. Alexey Bystrow, a Russian paleontologist and the species in honour of Schumann family. Bystrowiellas closest relative was Synesuchus.

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.

Capitosaurus is an extinct genus of temnospondyl amphibians whose remains have been found in Spitsbergen and Germany. Its skull was 30 cm long, with a total length over 122 cm. Several species have been assigned to the genus over the years, but only the type species C. polaris is still valid today.

Ceratites is an extinct genus of ammonite cephalopods. These nektonic carnivores lived in marine habitats in what is now Europe, during the Triassic, from the upper-most Anisian to the lower Ladinian age.

Chainosauria is a large clade of anomodont therapsids. It includes dicynodonts, dromasaurians and the basal taxa Patranomodon.

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.

The Chroniosuchidae are a family of semi-aquatic reptiliomorph amphibians found in sediments from the upper Permian and the upper Triassic periods, most in Russia. They were generally rather large animals, with long jaws similar to those found in modern crocodiles, and probably lived a similar life style as riverside piscivores and ambush predators. Like all Chroniosuchians, they bore extensive osteoderm armour on their backs, possibly as protection against terrestrial predators such as the Permian therapsids and the Triassic Rauisuchians.

Claraia is an extinct genus of scallop-like bivalve molluscs that lived from the Capitanian stage of the Late Permian to the Anisian stage of the Middle Triassic, 266-237 million years ago. Fossils have been found worldwide in North America, Europe, Asia, Africa, and Australia. These are common fossils subsequent to the Permian-Triassic boundary, suggesting that the genus experienced rapid diversification during and after the Permian–Triassic extinction event, around 251.4 million years ago.

Compsocerops is an extinct genus of temnospondyl amphibian that lived during the Late Triassic in what is now India, Argentina, Australia, South Africa and Brazil.

Derwentia is an extinct genus of trematosaurian temnospondyl within the family Rhytidosteidae. It is known from a single skull found from the Knocklofty Sandstone of Tasmania, which is Early Triassic in age.

Foreyia is an extinct genus of coelacanth lobe-finned fish which lived during the Middle Triassic period in what is now Canton of Graubünden, Switzerland. It contains a single species F. maxkuhni.

Gigatitan is an extinct genus of titanopteran insect that lived in Kyrgyzstan during the Triassic period. The type species is G. vulgaris, described by Aleksandr Grigorevich Sharov in 1968. Fossils of Gigatitan have been found in the Madygen Formation. In life, Gigatitan was a mantis-like predator with a wingspan of approximately 33 centimetres (13 in). Its forelimbs were similarly enlarged and bore spines for prey capture. The ovipositor of Gigatitan bore sharp cutting ridges. These were likely used to excise holes in plant matter for oviposition, similar to some modern Orthoptera. It is the type genus of the family Gigatitanidae, in which the closely related Nanotitan and Ootitan are also included.

Heterastridium is an extinct genus of marine hydrozoan. It is the only accepted genus in the monotypic family Heterastridiidae. The fossils date from the Upper Triassic. They are mostly discoid or spherical and some forms found in the Karakorum mountains are called Karakorum stones. They vary in diameter from 1 to 35 cm and appear to follow Cope's rule for the prehistoric climate.

The Mastodonsauroidea are an extinct superfamily of temnospondyl amphibians known from the Triassic and Jurassic. Fossils belonging to this superfamily have been found in North America, Greenland, Europe, Asia, and Australia. The genus Ferganobatrachus is included in this superfamily but not placed in any of the included families.

Polonodon is a non-mammaliaform eucynodont therapsid found in Poland from the Late Triassic known only from isolated teeth. It includes one species, Polonodon woznikiensis. It was part of the Dromatheriidae, which is an extinct family of prozostrodontian cynodonts.

Ramonalinidae is an extinct family of marine bivalve molluscs from the late Anisian. It was an edgewise-recliner with a flattened anteroventral surface and partially fused valves. They formed distinctive mud mounds.

Shansiodon is a genus of dicynodont from Middle Triassic of China and South Africa.

Sinokannemeyeria is a genus of kannemeyeriid dicynodont that lived during the Anisian age of Middle Triassic period in what is now Shanxi, China.

Spiriferina is an extinct genus of brachiopods that lived from the Late Silurian to the Middle Jurassic in Asia, Europe, North America, South America, and New Zealand.

Ticinepomis is an extinct genus of coelacanth lobe-finned fish which lived during the Middle Triassic period in what is now Canton Ticino, Monte San Giorgio, Switzerland. It contains a single species, T. peyeri. It was originally described as being a member of the family Coelacanthidae, being similar to Coelacanthus, Holophagus and Undina. Later, T. peyeri was placed in Latimeriidae. The recently discovered bizarre latimeriid Foreyia is thought to be T. peyeri's closest relative, as they share many features despite their drastically contrasting appearances.

Titanoptera is an extinct order of neopteran insects from the Triassic period. Titanopterans were very large in comparison with modern insects, some having wingspans of up to 36 centimetres (14 in).

Traversodontidae is a family of herbivorous cynodonts. Traversodonts were primarily Gondwanan, with many species known from Africa and South America. Recently, traversodonts have also been found from Europe and eastern North America. Traversodonts first appeared in the Middle Triassic and became extinct in the Early Jurassic diversifying in the Late Triassic. The family Traversodontidae was created by Friedrich von Huene in 1936 for cynodonts first found in São Pedro do Sul in Paleorrota, Brazil.

Wantzosaurus was a genus of temnospondyl amphibian of the Trematosauridae family. Fossils have been found in the Early Triassic Middle Sakamena Formation of what is now Madagascar. It showed adaptations for an almost completely aquatic lifestyle, having the ability to swim by lateral undulation. A pelagic lifestyle for this animal has been proposed.

Wetlugasaurus is an extinct genus of temnospondyl amphibian 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.

Xenacanthida is an order of prehistoric sharks that appeared during the Lower Carboniferous period. The order includes the families Xenacanthidae, Diplodoselachidae, and Orthacanthidae. The most notable members of the group are the genera Xenacanthus and Orthacanthus. Some Xenacanthida may have grown to lengths of 5 m (16 ft). Most forms had large serrated spines extending backwards from the neck. Xenacanthus had characteristic teeth. Most Xenacanthus died out at the end of the Permian in the Permian Mass Extinction, with only a few forms surviving into the Triassic period (Mooreodontus).
