Xenocretosuchus is a genus of tritylodont therapsids from the Aptian (Early Cretaceous) of Siberia, in the Russian Federation.[1] The type species, X. sibiricus, is known only from dental elements,[2] as is X. kolossovi, described in 2008.[3]
Alongside Montirictus,[4] it is the latest known non-mammalian synapsid (excepting the perhaps also not-mammalian[5][6] haramiyidan Avashishta[7][8]), extending their range to the Early Cretaceous.
