Callibrachion is an extinct genus of caseasaur. It was at least 1.5 metres (5 ft) in length. It lived during the Early Permian.
Discovery and history
It was originally described in 1893 on a basis of a specimen Early Permian deposits in northeastern France.[1] It was later considered a synonym of Haptodus by several authors, but subsequent examination has found it be a caseid rather a sphenacodont.[2] This was confirmed by cladistic analysis, which recovered Callibrachion as a basal caseid [3]
