Skeleton
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]
