Late Triassic synapsids of Europe

Lisowicia is an extinct genus of giant dicynodont synapsid that lived in what is now Poland during the late Norian or earliest Rhaetian age of the Late Triassic Period, about 210–205 million years ago. Lisowicia is the largest known dicynodont, as well as the largest non-mammalian synapsid, reaching about long, standing up to tall at the hips and weighing around , comparable in size to modern elephants. It was also one of the last dicynodonts, living shortly before their extinction at the end of the Triassic period. Fossils of a giant dicynodont were known from Poland since 2008, but Lisowicia

Eozostrodon is an extinct morganucodont mammaliaform. It lived during the Rhaetian stage of the Late Triassic. Eozostrodon is known from disarticulated teeth from South West England and estimated to have been less than in head-body length, slightly smaller than the similar-proportioned Megazostrodon.

Tricuspes is an extinct genus of cynodonts that lived in what would be Europe during the Triassic from 203.6 to 199.6 mya, existing for approximately . Three species are known: Tricuspes tubingensis (Huene, 1933), Tricuspes sigogneauae (Hahn et al., 1994) and Tricuspes tapeinodon (Godefroit and Battail, 1997), which are all from the Late Triassic (Rhaetian) period in continental Europe.

Theroteinus is an extinct genus of haramiyidan mammaliaforms from the Late Triassic of France and Britain. It contains three species: T. nikolai, T. rosieriensis and T. jenkinsi, the former two of which are known exclusively from teeth found at the sand quarry of Saint-Nicolas-de-Port, while T. jenkinsi is known from a bedded sequence belonging to the Westbury Formation in a road cutting near Holwell, Dorset. Theroteinus is the only member of the family Theroteinidae and the suborder Theroteinida.

Kuehneotherium is an early mammaliaform genus, previously considered a holothere, that lived during the Late Triassic-Early Jurassic Epochs and is characterized by reversed-triangle pattern of molar cusps. Although many fossils have been found, the fossils are limited to teeth, dental fragments, and mandible fragments. The genus includes Kuehneotherium praecursoris and all related species. It was first named and described by Doris M. Kermack, K. A. Kermack, and Frances Mussett in November 1967. The family Kuehneotheriidae and the genus Kuehneotherium were created to house the single species Ku

Woutersia was a Triassic genus of 'symmetrodont' and the only representative of the family Woutersiidae. It was originally classified as a kuehneotheriid, but it has been suggested that it may be related to Docodonta. Remains of W. mirabilis and W. butleri have been found in the Gres à Avicula contorta Formation at Saint-Nicolas-de-Port, France, while W. mirabilis has been found in Varangéville, France; remains have been dated to the Late Triassic, 205.6 to 201.6 Ma.

Gornogomphodon is an extinct genus of cynodonts from the Gorno Formation of Bergamo, Italy. It existed during the Middle Carnian age of the Late Triassic (around 216.5 to 228.0 million years ago). It contains only one species: Gornogomphodon caffi.

Polonodon is an extinct genus of dromatheriid cynodonts that lived in what is now Poland during the Carnian stage of the Late Triassic. It includes one species, Polonodon woznikiensis, which is known only from isolated teeth.

Hallautherium is an extinct genus of morganucodont mammaliaforms from the Late Triassic of Europe. The type species H. schalchi is known from the Klettgau Formation of Switzerland. In addition, a molariform tooth referable to the genus has been found in Poland.
