Cast of skull OH 24 nicknamed ‘Twiggy’ – a 1.8-million-year-old skull discovered in 1968 by Peter Nzube in Olduvai Gorge, Tanzania. When found, this skull had been badly crushed and was reconstructed from hundreds of fragments. It also shows some distortion of the bones that occurred before fossilisation was complete.

Characteristics of Homo habilis can be seen on this skull including a brain case that was fuller and more rounded due to expansion of the brain, the beginnings of a slight forehead, a face with a small arched brow ridge, and teeth that were smaller and more human-like but with incisors that were still relatively large.
