Which large mammal that appears in the engraving for the Wildebeest Kuil Rock Art Centre, is one of any five extant species of odd-toed ungulates in the family Rhinocerotidae?
Rhinoceros A rhinoceros ( , , ), often abbreviated to rhino, is one of any five extant species of odd-toed ungulates in the family Rhinocerotidae, as well as any of the numerous extinct species. Two of the extant species are native to Africa and three to Southern Asia.
Macraucheniidae Macraucheniidae is a family in the extinct South American ungulate order Litopterna, with similarities to the camel and rhinoceros. The reduced nasal bones of their skulls suggest that they may have had a small proboscis, or trunk. Their hooves were similar to those of rhinoceroses today, with a simple ankle joint and three digits on each foot. Thus, they may have been capable of rapid directional change when running away from predators, such as large phorusrhacid terror birds, sparassodont marsupials, and saber-toothed cats ("Smilodon"). Macraucheniids probably lived in large herds to gain protection against these predators, as well as to facilitate finding mates for reproduction.
