Collared peccary Dicotyles tajacu, photographed by Colin Burnett.

Belongs within: Artiodactyla.
Contains: Listriodontinae, Suinae, Sanitheriinae, Hyotherium.

The Suinamorpha unites the pigs (Suidae) and the peccaries (Tayassuidae). Members of this clade have an elongate, mobile, cartilaginous snout with a flattened terminal area around the nostrils (Cooke & Wilkinson 1978). In the modern fauna, the Suidae are native to the Old World while the Tayassuidae are restricted to the New World, but the fossil record indicates that Tayassuidae were previously present in the Old World from the Oligocene to Pliocene. Modern peccaries are generally sociable animals, though the chacoan peccary Catagonus wagneri forms only small groups of up to ten individuals. The white-lipped peccary Tayassu pecari, in contrast, can form herds of over 100 individuals.
