Homo habilis
Artist's rendering of Homo habilis, which lived from 2 to 1.5 million years ago.
The oldest Homo habilis remains discovered at Olduvai Gorge are dated to approximately 1.8 to 1.9 million years ago (mya). Among these early specimens is OH 24, a relatively complete but distorted cranium. Other significant finds from the site, such as OH 7 and OH 62, are also associated with these early deposits, though they are noted as being slightly less ancient than the oldest remains.123
