Arctosuchus is an extinct genus of gorgonopsid from the Lopingian (Permian). The type species, A. tigrinus, is from the Teekloof Formation (Tropidostoma Assemblage Zone),[1][2][3] although a second species, A. buceros, from the Wolfville Formation (Upper Wolfville Member) of Nova Scotia, Canada, may also belong to the genus, but it is from the Triassic and it probably instead belongs to an indeterminate synapsid.[4]
