Scylacosauridae is an extinct family of therocephalian therapsids. Scylacosaurids lived during the Permian period and were among the most basal therocephalians.^[3] The family was named by South African paleontologist Robert Broom in 1903.^[4] Scylacosaurids have long snouts and unusual saber-like canine teeth.^[5]
