 These features contrast with those of the average robust australopithecine.SK 847 also has a short palate and a small temporomandibular joint that could only fit a small, short lower jaw and not the typically massive mandible of a robust australopithecine.In 2010, another argument was made by Darren Curnoe suggesting that SK 847 along with many other fossil specimens, including some from "Homo habilis", "Homo ergaster", and Australopithecus species, obtained from South Africa gives evidence to a whole new hominin species called "Homo gautengensis", which he believes is the earliest species of the genus "Homo".
