Peraiocynodon is an extinctmammaliaform from the orderDocodonta, found in the Middle Jurassic rocks of the United Kingdom. It is only known from isolated molar teeth found in the mammal bed atKirtlington cement quarry in Oxfordshire, England (Forest Marble Formation).
Peraiocynodon was originally erected in 1928 with a single species named,[1] but it was later considered to be a synonym ofDocodon.[2] However, in 2003, the genus was resurrected and a new species,P. major, was described based on new teeth found atKirtington Cement Quarry in Oxfordshire.[3] It remains uncertain whether one or both of these species ofPeraiocynodon may be thedeciduous teeth of another genus of docodontan, or whether they truly are separate species. In 2004, Alexander Averianov synonymisedP.major withKrusatodon kirtlingtonensis.[4]
