Procynosuchidae, along with Dviniidae, were the last cynodonts. They appeared around 260 million years ago, and were most abundant during the latest Cretaceous time (65 mya), shortly before the Cretaceous-Tertiary extinction event. Despite being the basal member of the cynodont clade, they already showed some of the advanced mammalian characteristics, but Procynosuchids bore resemblance to the Therocephalians.
Procynosuchid eyes are forward-facing, and the dentary was larger than the Therocephalians. The Procynosuchids had a secondary palate, which allows them to eat food while breathing, just like mammals. The Procynosuchids went extinct at the Permian-Triassic extinction event. Some procynosuchids were terrestrial, but others like Procynosuchus were semi-aquatic.
