''Xenocretosuchus'' is a genus of probable tritylodont therapsids from the Aptian (Early Cretaceous) of Siberia, in the Russian Federation.〔(Fossilworks. "Xenocretosuchus." Retrieved from )〕 The type species, ''X. sibiricus'', is known only from dental elements,〔(Palaeos. "Cynodontia: Tritylodontidae." Retrieved from )〕 as is ''X. kolossovi'', described in 2008.〔Lopatin & Agadjanian, 2008. "A Tritylodont (Tritylodontidae, Synapsida) from the Mesozoic of Yakutia." Retrieved from ()〕 The placement of this animal is controversial,〔 but if it is a tritylodont, then it is the latest known non-mammalian synapsid, extending their range to the Early Cretaceous. ==References==
