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 cladistic analysis has found it be a caseasaurian rather a sphenacodont.[2]
