About Mylohyus
Mylohyus is an extinct genus of peccary found in North and Central America. It first evolved during the Late Miocene and became extinct at the end of the Pleistocene, around 12,000 years ago, during the Late Pleistocene megafaunal extinction.
Six species were known, the most famous being Mylohyus nasutus, also known as the long-nosed peccary. It went extinct at the end of the Rancholabrean North American land mammal age. The genus was slightly larger-bodied than any modern peccaries, with an estimated mass of 68 kg (150 lb).
