Cradle of Humankind
The Cradle of Humankind, the only area "P. robustus" is known from, was mainly dominated by the springbok "Antidorcas recki", but other antelope, giraffes, and elephants were also seemingly abundant megafauna. Other known primates are early "Homo", the Hamadryas baboon, and the extinct colobine monkey "Cercopithecoides williamsi".
