Platygonus


Platygonus
is an extinct genus of herbivorous peccaries of the family Tayassuidae, endemic to North and South America from the Miocene through Pleistocene epochs, existing for about.

Description

Platygonus were gregarious animals and, like modern peccaries, possibly traveled in herds. At least nine known species of Platygonus are known and ranged from southern Canada to Mexico and from California to Pennsylvania. Stratigraphically, they occur throughout the Pleistocene, and as early as the Blancan in the Gelasian of the Pliocene. The most recent credible date obtained for some species remains is about 11,000 BP. They probably appeared very similar to their closest living relative, the Chacoan peccary.

Taxonomy

Platygonus was named by John Lawrence LeConte in 1848 for fossils found in Pleistocene karst deposits in Illinois, which are now preserved in the Academy of National Sciences in Philadelphia.
The following species of Platygonus have been described:
Most Platygonus species were similar in size to modern peccaries especially giant peccary, at around in body length, and had long legs, allowing them to run well. They also had a pig-like snout and long tusks which were probably used to fend off predators. They had a complex digestive system, similar to that of a modern ruminant.
