The late Piacenzian may be when the genus "Homo" developed out of the ancestral genus "Australopithecus". While the oldest known fossils unambiguously identified as "Homo habilis" date to just after the end of the Piacenzian (2.58 Ma), a fossilized jawbone that exhibits traits that are transitional between "Australopithecus" and "Homo habilis" was discovered in the Afar Triangle in 2015.
