Peraiocynodonis an extinctmammaliaformfrom 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 atKirtlingtoncement quarry in Oxfordshire, England (Forest Marble Formation).
Peraiocynodonwas originally erected in 1929 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 Quarryin Oxfordshire.[3]It remains uncertain whether one or both of these species ofPeraiocynodonmay be thedeciduous teethof another genus of docodontan, or whether they truly are separate species.
