"Batrachotomus" was a heavily built, large quadrupedal reptile reaching in length. A trait that characterized "Batrachotomus", compared to other crurotarsans, was a series of paired small plates on its back which were attached to each vertebra. These bony deposits forming scales are called osteoderms. Flattened and leaf-shaped, these extended from behind the head along the column and reducing in size, ended at the tail. There is also evidence that osteoderms were present on the ventral region of the tail, as seen in "Ticinosuchus ferox", and even on the flank, belly and limbs.
