Paritatodon is an extinct mammaliaform which existed in Kyrgyzstan and England during the Jurassic period.[1] It was originally the holotype specimen of Shuotherium kermacki, but Martin and Averianov (2010)[1] argued that it resembled the genus Itatodon (Docodonta) and so renamed it Paritatodon.

Binomial name
Paritatodon kermacki
(Sigogneau-Russell, 1998)

Nonetheless, some recent phylogenetic studies assign it (and Itatodon) to Shuotheriidae,[2] while others continue to consider the taxon a docodont.

Like many Mesozoic mammals, this species is only known from its teeth, in this case two lower molars from the Forest Marble Formation in England,[3] and a single left lower molar from the Balabansai Formation in the Fergana Depression, Kyrgyzstan.[1]
