The long-nosed peccary (Mylohyus nasutus) is an extinct mammal species of the peccary family (Tayassuidae). It is one of two peccary-species that existed in the US-Midwest during the last ice age.[1]


The long-nosed peccary was about 0,75 m (2,5 ft) in height and 67 kg (148 lb) in weight.[2] It had an elongated facial region and long slender legs.[3]

Habitat and distribution[edit]

During the last glacial, long-nosed peccaries were distributed throughout eastern 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.

Ecology and behavior[edit]

Unlike the flat-headed peccary, the long-nosed peccary was probably a solitary animal and did not frequent caves.[4]
