Some of the teeth survived, but the cranium was broken into many small fragments only the top of the braincase, or vault, has been pieced back together. Just a month later a third skull was found, but the bones had been trampled by cattle after being washed into a gully. Pieces of another thin-walled cranium along with upper and lower jaws and teeth came to light in 1963. The fossil evidenceĪpart from the original discovery of the 1.8-million-year-old jaw, cranial, and hand bones from a juvenile individual called Olduvai Hominid 7 (OH 7), additional fossils from Olduvai have been ascribed to H. habilis extremely important, even though there are few remnants of it. All these characteristics foreshadow the anatomy and behaviour of H. As justification for designating their new creature Homo rather than Australopithecus, they described the increased cranial capacity and comparatively smaller molar and premolar teeth of the fossils, a humanlike foot, and hand bones that suggested an ability to manipulate objects with precision-hence the species name Homo habilis, or “handy man.” Furthermore, simple stone tools were found along with the fossils. Formal announcement of the discoveries was made in 1964 by anthropologists Louis S.B. As more specimens were unearthed at locations such as Koobi Fora in northern Kenya, researchers began to realize that these hominins were anatomically different from Australopithecus, a genus of more-apelike creatures whose remains had been found at many African sites. The first confirmed remains found at Olduvai consist of several teeth and a lower jaw associated with fragments of a cranium and some hand bones.
