Platygonus was 1 m (3 ft, 4 in) long (larger than modern peccaries) and had long legs, allowing it to run well. It also had a pig-like snout and long, carnivore-like tusks which were probably used to fend off predators. Platygonus's digestive system was very complex, more similar to that of a ruminant.
