Triassic temnospondyls of Europe

Mastodonsaurus (meaning "teat tooth lizard") is an extinct genus of temnospondyl amphibian from the Middle Triassic of Europe. It belongs to a Triassic group of temnospondyls called Capitosauria, characterized by their large body size, large flattened skulls, and probably mainly aquatic lifestyles. Mastodonsaurus remains one of the largest amphibians known, and may have exceeded 6 meters (20 feet) in length.

Gerrothorax ("wicker chest") is an extinct genus of temnospondyl amphibian from the Triassic period of Greenland, Germany, Poland, Sweden, and possibly Thailand. It is known from a single species, G. pulcherrimus, although several other species such as G. pustuloglomeratus have been named in the past.

Metoposaurus meaning "front lizard" is an extinct genus of stereospondyl temnospondyls, known from the Late Triassic of Germany, Italy, Poland, and Portugal. This animal was mostly aquatic, possessing 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.

Cyclotosaurus is an extinct genus of temnospondyl within the family Mastodonsauridae. It was of large size for an amphibian, having a skull length of about .

Capitosaurus is an extinct genus of temnospondyl from the Late Triassic of Germany. Its skull was 30 cm long, with a total length over 122 cm. It was one of the first temnospondyl genera to have been erected, with the type species, C. arenaceus, originally described by Münster in 1836 based on a partial skull from the earliest Upper Triassic of Bavaria, Germany. Numerous other species were referred to Capitosaurus before the 1920s, but through much of the 20th century most authors considered the original specimen of C. arenaceus to be undiagnostic, effectively invalidating the genus

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.

Wetlugasaurus (meaning "Vetluga River lizard") 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 long skull, and reached a total length of .

Parotosuchus is an extinct genus of capitosaurian temnospondyls within the family Mastodonsauridae. Fossils are known from the Early Triassic of Europe, Africa, Australia, and Antarctica. It was about long and likely lived in aquatic environments such as lakes and rivers. Parotosuchus was covered in a scaly skin, unlike the smooth skin of modern-day amphibians, and probably moved with an eel-like motion in the water.

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.

Sclerothorax is an extinct genus of temnospondyl from the Early Triassic of Germany. It is distinguished from other temnospondyls by its short and very wide skull and the elongated neural spines that form a ridge along its back. Sclerothorax is a basal member of Capitosauria, a large clade of temnospondyls that lived throughout the Triassic.

Eocyclotosaurus (Greek 'èoos' = dawn, 'kyklos' = circle, 'ous' = ear ) 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.

Plagiosaurus is an extinct genus of temnospondyl amphibian. The type and only species is P. depressus, first described by Otto Jaekel in 1914. Arthur Smith Woodward regarded the genus as a synonym of Plagiosternum, but most researchers consider it to be valid. It was paedomorphic, retaining the larval gills in adulthood. Like many stereospondyls, it had weak simplified vertebrae, consisting of large intercentra and neural arches, which is known as the stereospondylous condition.

Tupilakosaurus is an extinct genus of dvinosaurian temnospondyl within the family Tupilakosauridae.

Trematolestes is an extinct genus of temnospondyl amphibian from the Lower Keuper (Ladinian, Middle Triassic) of southern Germany. It was first named by Rainer R. Schoch in 2006 and the type species is Trematolestes hagdorni. It is the first trematosaurid represented by a nearly complete skeleton. thumb|left|Restoration

Plagiosuchus is an extinct genus of plagiosaurid temnospondyl. It is known from several collections from the Middle Triassic of Germany.
