Neotrirachodon is an extinct genus of synapsid which existed in Russia during the Middle Triassic period. It contains the species Neotrirachodon expectatus.[3]
It is known from a jaw fossil consisting of the left dentary with postcanines. It was recovered from the Donguz Formation, Orenburg Oblast of Russia.[4][5] The fossil was first described as belonging to the genus Antecosuchus (as Antecosuchus ochevi), a traversodont.[4]
It has tentatively been classified as a trirachodontid gomphodont pending further fossil discoveries. Gomphodonts (or tritylodonts) are herbivorous cynodonts.[6] If correct, it would be the first trirachodontid described from Russia.[4]
Its classification remains uncertain, however. Other studies treat it as an incertae sedis gomphodont, while others propose that it is more likely to be a bauriid therocephalian rather than a trirachodontid.[7]
