The 1 m (3 ft 4 in) long creature is thought to have been amphibious, as all species possessed an elongated, barrel-shaped body and short limbs that are typical adaptations found in semi-aquatic mammals. P. superbus had a long tapir-like face, while P. carrikeri had a short, somewhat pig-like face.[2]
