Platygonus compressus, the flat-headed peccary, is an extinct mammal species from the Tayassuidae-family, that lived in North-America during the Pleistocene. It was first described in 1848 by John L. Leconte. At the end of the Pleistocene it disappeared.
The flat-headed peccary was about 75 cm (29.5 in) in shoulderheight and about 30 kg (66.1 lb) in weight. Other sources have estimated it to be similar in size to the European Wild Boar. Sizes differ between the place they have been found.
Fossil skulls suggest a small brain, but a good sense of smell and seight. It has been suggested that the nasal cavity provided filtration for cold, dry and dusty air.Platygonus compressus had elongated limbs, a short humerus, broad and erect thoracic vertebrae and a large scapula. Therefore it has been suggested that this species may have been fleeter on foot that modern peccary species. Otherwise they probably appeared very similar to their closest living relative, the Chacoan peccary.
