Metridiochoerus is an extinct genus of swine known from the Pliocene and Pleistocene of Africa. It is also known as the giant warthog.

Chronology

[edit | edit source]

The oldest specimen dates to around 3.4 million years ago from the Usno Formation in Ethiopia.[1] It probably evolved from a recent immigrant from Eurasia, which has been suggested to be the European "Postpotamochoerus" provincialis.[2] The youngest remains of the genus date to the Late Pleistocene in southern Africa (Zimababwe, and possibly South Africa).[3]

Description

Restoration

Metridiochoerus was a large animal, 1.5 metres (4.9 ft) in length, resembling a giant warthog. It had two pairs of large tusks which were pointed sideways and curved upwards.[4] The teeth, especially the third molars, become increasingly high-crowned (hypsodont) in later species.[1]

Biology

[edit | edit source]

The various species are usually thought to have been grazers,[3] though this has been questioned for the earliest, low-crowned species.[1]
