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 4 million years.^[1] 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.

Places of discovery

Teeth of Tricuspes tubingensis have been found at the following locations:

• Saint-Nicolas-de-Port^[2]
• Medernach^[2]
• Baden-Württemberg^[2]
• Kanton Schaffhausen^[2]

Dentition

This genus is represented only by isolated teeth found in continental Europe. Its postcanine molariform teeth are tricuspate or tetracuspate and the tooth roots are incipiently divided.
