Fore feet with the functional toes reduced to two, the second and third, of equal length, with closely united metacarpals and short, sharp, slightly curved, compressed claws.
- The three fingers and their metacarpals remain separate, each with a claw.
- Metacarpals fused.
The Saururae have the metacarpals well developed and not ancylosed, and the caudal vertebrae are numerous and large, so that.
The second genus, Dorcatherium (or Hyomoschus), is African, and distinguished chiefly by the feet being stouter and shorter, the outer toes better developed, and the two middle metacarpals not welded together.
