''Erythrosuchus'' (''red crocodile'') is an extinct genus of archosauriform reptile from the Triassic of South Africa and Namibia. Remains have been found from the Cynognathus Assemblage Zone of the Beaufort Group in the Karoo of South Africa as well as the Omingonde Formation in Namibia. In the Late Triassic, the ecological niche left by ''Erythrosuchus'' was filled by creatures like ''Saurosuchus'' and ''Postosuchus''. ==Description== ''Erythrosuchus'' was the largest predator of its time, at around long,〔 and tall. It walked on all fours and had limbs which were positioned semi-vertically under its body, unlike the more sprawling gait of most earlier reptiles. Its head was large and dinosaur-like, reaching a length of , and had sharp, conical teeth. ''Erythrosuchus'' was the largest erythrosuchid, but apart from its size, it was similar in appearance to other related genera. It had a large head and comparatively short neck. One of the few distinguishing features of ''Erythrosuchus'' other than its size is the smoothness of the margin of the squamosal, a bone at the rear of the skull. In other erythrosuchids, the margin of this bone projects backward from the skull, giving it a hook-like appearance. In ''Erythrosuchus'', the margin is convex and lacks a hook.
