Therioherpetidae
Therioherpetidae is an extinct family of threrapsids. It is based on Therioherpeton cargnini, a small cynodont who lived in the Triassic and was collected in Santa Maria, Santa Maria Formation, the Geopark of Paleorrota, Brazil. This family consists of small carnivores presenting features of the basal mammal Morganucodon.
For this characteristic Therioherpeton was touted as a likely ancestor of mammals.
