. Due to the lack of fossil material or even specimens from archeological sites, it was assumed that javelinas only recently crossed into the US by way of Mexico. However, a fossil jaw of this species was discovered in Florida ("Collared peccary (Mammalia, Artiodactyla, Tayassuidae, Pecari) from the late Pleistocene of Florida", Richard C. Hulbert, Gary S. Morgan & Andreas Kerner), proving that at some point in the late Pleistocene the species had already inhabited part of the Southern US.

Behavior

Collared peccaries are diurnal creatures that live in groups of up to 50 individuals, averaging between six and nine animals. They sleep in burrows (often under bushes or larger systems of tree roots), but sometimes can be found in caves, abandoned mines, old desert tunnels, or among logs, felled trees and abandoned timber. However, collared peccaries are not completely diurnal. In central Arizona, they are often more active at night, and less so in the heat of the daytime. Although they usually ignore humans, they will react if they feel threatened. They defend themselves with their tusks. A collared peccary can release a strong musk or give a sharp bark if it is alarmed. Amazonian peoples (including the Shipibos) sometimes raise and tame juvenile collared peccaries, if they are encountered. Peccary will also rub their scent onto rocks and tree stumps to mark their territory, and rub the scent on each other to help with identification.
