The long-nosed peccary (Mylohyus nasutus) is an extinct mammal species of the peccary family (Tayassuidae). It went extinct at the end of the Rancholabrean North American Land Mammal Age.[1]: 21

Description
editThe long-nosed peccary was about 0.75 metres (2.5 ft) in height and 67 kilograms (148 lb) in weight.[2] It had an elongated face, long, thin legs and dewclaws.[1]: 21
Habitat and distribution
editDuring the last glacial, long-nosed peccaries, sensu lato, were distributed throughout southeastern North America with concentrations in Appalachia and Florida. Most fossil localities containing this species are found in the southern and south-eastern U.S., from west Texas to Florida, and north to Pennsylvania. Mylohyus nasutus, if considered to be a different species than M. fossilis, occupied the western part of this range, but their classification as separate species is disputed.[1]: 22–23 According to Lundelius, these species or forms co-occur in the Cumberland Cave deposits in Maryland.[3]: 34
Ecology and behavior
editUnlike the flat-headed peccary, Platygonus compressus, the long-nosed peccary was probably a solitary animal and did not frequent caves.[4]
