The Stuttgart Formation is a geologic formation in Germany. It preserves fossils dating back to the Carnian stage of the Triassic period. [1]
Zanclodon is an extinct genus of archosauriform from the Erfurt Formation in southern Germany. It was once a wastebasket taxon until a taxonomic revision by Schoch (2011) left only the paratype within Zanclodon laevis proper. The type species is Z. laevis.
Mastodonsaurus is an extinct genus of temnospondyl from the Middle Triassic of Europe. It belongs to a Triassic group of temnospondyls called Capitosauria, characterized by their large body size and presumably aquatic lifestyles. Mastodonsaurus remains one of the largest amphibians known, and may have exceeded 6 meters in length.
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.
Cyclotosaurus is an extinct genus of temnospondyl within the family Mastodonsauridae. It was of great size for an amphibian, had an elongated skull up to 56 cm (22 in).
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.
Mastodonsauridae is a family of capitosauroid temnospondyls. Fossils belonging to this family have been found in North America, Greenland, Europe, Asia, and Australia. The family Capitosauridae is synonymous with Mastodonsauridae.
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).
The Trossingen Formation, formerly the Knollenmergel, is a geological formation in Germany and Switzerland. It dates back to the late Norian-Rhaetian.
Plagiosuchus is an extinct genus of plagiosaurid temnospondyl. It is known from several collections from the Middle Triassic of Germany.
Dyoplax is an extinct genus of pseudosuchian archosaur, possibly an erpetosuchid. Fossils have been found from the type locality within the upper Schilfsandstein Formation in Stuttgart, Germany. The holotype specimen was a natural cast of a nearly complete skeleton that lacked only parts of the tail and limb bones.
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 Bromsgrove Sandstone is a geologic formation of the Sherwood Sandstone Group in England. It preserves fossils and ichnofossils of Chirotherium barthii, and Chirotherium sickleri, dating back to the Middle Triassic (Anisian) period.
The Röt Formation or Rötton Formation, or Upper Buntsandstein, is a geologic formation of the Buntsandstein in Germany. It preserves fossils dating back to the Middle Triassic Epoch. The formation overlies the Plattenstein and Solling Formations and is overlain by the Jena Formation.
The Exter Formation is the only formation of the Upper Keuper or Rhätsandstein, and is a geologic formation in Germany. It preserves fossils dating back to the Rhaetian of the Triassic period.
The Hassberge Formation is a geologic formation in Bavaria, Germany. It preserves fossils dating back to the Carnian stage of the Triassic period.
The Corona Formation is a geologic formation of the Carnian Alps at the border of Austria and Italy. It preserves fossils dated to the Gzhelian stage of the Late Carboniferous period.
The Werfen Formation is a geologic formation in the Southern Limestone Alps and Dinaric Alps of Austria, Bosnia and Herzegovina, and Italy. It preserves fossils dating back to the Triassic period.
Cyclotosaurus buechneri is a species of the temnospondyl genus Cyclotosaurus from the Upper Triassic of northwestern Germany.
The Bukobay Svita is a Middle Triassic geological unit in Russia. It is composed primarily of red or grey lacustrine sediments, reconstructing a humid and marshy depositional environment. Bukobay is the youngest section of a Triassic terrestrial succession exposed south of the Ural Mountains. It is equivalent to a biostratigraphic unit, the Bukobay Gorizont, which is also called the "Bukobay Horizon" or "Mastodonsaurus" fauna).
