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.
Termatosaurus is a potentially dubious genus of archosaur known from several tooth specimens. Its remains come from the Upper Triassic of France, England, Germany and Switzerland. Termatosaurus was once thought to have survived until the Early Jurassic, but the attributed Jurassic remains were redescribed as plesiosaur material. Two species are known of this animal: the type species, T. albertii, named by Meyer and T. Plieninger in 1844, and T. crocodilinus, by Quenstedt (1858).
Plagiosternum was a middle Triassic temnospondyl that is native to Spitzbergen.
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.
Bromsgroveia is an extinct genus of predatory ctenosauriscid archosaur from the Middle Triassic Bromsgrove Sandstone of England. Ctenosauriscids were a group of rauisuchians that was related to the ancestors of modern crocodiles and alligators.
Californosaurus is an extinct genus of ichthyosaur, an extinct marine reptile, from the Lower Hosselkus Limestone of California, and also the Muschelkalk of Germany.
The Toretocnemidae were a group of ichthyosaurs that lived in the Late Triassic period.
Ctenosauriscidae is an extinct family of pseudosuchian archosaurs within the clade Poposauroidea. Ctenosauriscids existed in Africa, Asia, Europe and North America during the Early Triassic to the Middle Triassic period. All species had large "sails" on their backs. Ctenosauriscids are among some of the earliest archosaurs and represent the first global radiation of the group.
Leptonectes is a genus of ichthyosaur that lived in the Late Triassic to Early Jurassic. Fossils have been found in Belgium, Germany, Switzerland, Spain and the United Kingdom. The type species, L. tenuirostris, reached 4 metres (13 ft) long, while L. moorei reached 3 metres (9.8 ft) long; the largest species, L. solei, was approximately 5–6 metres (16–20 ft) long.
Trematosauridae is a family of large marine temnospondyls with several included genera.
Hyperokynodon is an extinct genus of trematosaurian temnospondyl within the family Trematosauridae. Fossils have been found in Germany. While most trematosaurids existed during the Early Triassic, Hyperokynodon has been found in Late Triassic deposits, making it the youngest known trematosaurid. Hyperokynodon was known since 1852, but it was not identified as a trematosaurid until 1987. The type and only species is H. keuperinus.
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.
Callawayia is an extinct genus of ichthyosaur. It contains the species Callawayia neoscapularis.
Hudsonelpidia is an extinct genus of small parvipelvian ichthyosaur known from British Columbia of Canada.
Qianichthyosaurus is an extinct genus of ichthyosaur from the Ladinian and Carnian stages of the Late Triassic epoch. Its fossils have been found in southeastern China, in Carnian rocks of the Falang Formation near Huangtutang, Guizhou. The type species is Qianichthyosaurus zhoui, named by Chun Li in 1999. A second species, Qianichthyosaurus xingyiensis, was named from older (Ladinian) deposits in the Falang Formation in 2013 by Pengfei Yang and colleagues. Complete Qianichthyosaurus fossils are common in the Xiaowa Formation, with both juveniles and pregnant specimens being known; its larger contemporaries, Guizhouichthyosaurus and Guanlingsaurus, are rarer.
Cymbospondylidae is an extinct family of hueneosaurian Ichthyosaurs known from the Middle Triassic of Europe, North America, and Asia.
Macgowania is an extinct genus of parvipelvian ichthyosaur known from British Columbia of Canada. It was a small ichthyosaur around 3 metres (9.8 ft) in total body length.
Parvipelvia is an extinct clade of euichthyosaur ichthyosaurs that existed from the Late Triassic to the early Late Cretaceous of Asia, Australia, Europe, North America and South America. Named by Ryosuke Motani, in 1999, it contains the basal taxa like Macgowania and Hudsonelpidia. Maisch and Matzke (2000) found in their analysis seven synapomorphies that support Parvipelvia. They also found 10 synapomorphies that support the existence of post-Triassic clade of ichthyosaurs, for which the name Neoichthyosauria was found to be available. Parvipelvians were the only ichthyosaurs to survive the Triassic-Jurassic extinction event.
Callistomordax is an extinct genus of temnospondyl amphibian from the Middle Triassic of Germany. The type and only species, Callistomordax kugleri, was named in 2008. It is known from several well-preserved skeletons found in the Erfurt Formation, part of the Lower Keuper, which dates back to the late Ladinian stage.
The Hueneosauria are a group of Ichthyosauria, living during the Mesozoic.
