Scylacosauridae is an extinct family of therocephalian therapsids. Scylacosaurids lived during the Permian period and were among the most basal therocephalians. The family was named by South African paleontologist Robert Broom in 1903. Scylacosaurids have long snouts and unusual saber-like canine teeth. Most scylacosaurids went extinct during the Capitanian mass extinction, with only Alopecognathus and Pristerognathus persisting into the Late Permian. While most scylacosaurids were known from the Karoo Basin of South Africa, Julognathus was found within the Sundry Assemblage of Eastern Europe.
