Erythrosuchidae (meaning "red crocodiles") are a family of large basal archosauromorph carnivores that lived from the later Early Triassic (Olenekian) to the early Middle Triassic (Anisian). Their fossil remains are known so far from South Africa (Beaufort Group of the Karoo Basin), the Perm region of Russia, and China. They were the apex predators of their day, with lengths of 2.5 to over 5 meters. In the largest forms, such as Erythrosuchus, the skull alone can be a meter in length. The large contemporary Kannemeyeriid dicynodonts doubtless constituted much of their prey. However, the first Erythrosuchids appear in the fossil record slightly earlier than the Kannemeyeriids do, so it must be assumed that they also fed on other animals as well.
