Xenocretosuchus is a genus of probable 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]
The placement of this animal is controversial,[2] but if it is a tritylodont, then it is the latest known non-mammalian synapsid, extending their range to the Early Cretaceous.
