Platygonus compressus

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 wild boar. Sizes differ between the places they have been found. Fossil skulls suggest a small brain, but a good sense of smell and sight. 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 than modern peccary species. == Distribution and habitat ==

The flat-headed peccary was widespread throughout North America. Fossils have been found from what is now New York to California, Wisconsin to Mexico and further south in South America. An Individual has even been found as far north as the Yukon. Platygonus compressus lived in a great variety of habitats and had a wide environmental climate tolerance. This species was known to have roamed North American boreal forests and tropical rainforests in South America. Flat-headed peccary remains were found in Hastings Highlands, Ontario, along with remains of american mastodons. At Megenity Peccary Cave in Indiana, remains of over 650 individual flat-headed peccaries have been found. Of the Indiana site, a paleontologist noted: “So the question is then: did they live here? Or did they all have a misfortune and die here? It’s a little of both, but it’s mainly that they probably inhabited this cave and rock shelter for most of that time period.” At Bat Cave in Missouri 98 individuals have been found together. Caves could possibly have been used for protection from extreme weather. == Ecology ==

Flat-headed peccarys are often found in small groups up to 12 individuals. It is likely that Platygonus compressus lived in varying herd numbers from 2-100, as well as modern peccary species. It is believed to have been an open forest browser. Fossil teeth show adaptation for coarser vegetation. == References ==
