The Dmanisi skull, also known as Skull 5 or D4500, is one of five skulls discovered in Dmanisi, Georgia and classified as early Homo erectus.Described in a publication in October 2013, it is estimated to be about 1.8 million years old and is the most complete skull of a Pleistocene Homo species, [1] [2] and the first complete adult hominin skull of that degree of antiquity.
KNM ER 1813 is a skull of the species Homo habilis.It was discovered in Koobi Fora, Kenya by Kamoya Kimeu in 1973, and is estimated to be 1.9 million years old.. Its characteristics include an overall smaller size than other Homo habilis finds, but with a fully adult and typical H. habilis morphology.
D4500's features are very rare compared to early Homo in that it had a small braincase yet an unusually large prognathic face. [2] "Skull 5" has an accompanying mandible, D2600, which was found in 2000. In 1999 two other skulls had been found at the same site—D2280 and D2282. D2280 was a near-complete brain-case with 780 cc brain-size.
The researchers found that the Dmanisi hominins "cannot unequivocally be referred either to H. habilis or to H. erectus" and that there, in regards to early Homo, was a "continuum of forms"; Skull 5 appears to share many primitive features with H. habilis whereas Skull 1, with the largest brain, is more similar to African H. ergaster/H. erectus ...
Homo habilis (lit. 'handy man') is an extinct species of archaic human from the Early Pleistocene of East and South Africa about 2.4 million years ago to 1.4 million ...
OH 24 (Olduvai Hominid No. 24, nicknamed "Twiggy") is a fossilized skull of the species Homo habilis. It was discovered in Olduvai Gorge , Tanzania by Peter Nzube in 1968. The skull was found crushed almost flat and was therefore named after the famously skinny model of the time Twiggy .
KNM ER 1805 is the catalog number given to several pieces of a fossilized skull of the species Homo habilis. It was discovered in Koobi Fora, Kenya in 1974. The designation indicates specimen 1805, collected from the east shore of Lake Rudolf (now Lake Turkana) for the Kenya National Museums. It is estimated to be 1.74 million years old.
SK 847 is the abbreviated designation for the fossilized fragments of a Homo habilis cranium, discovered in South Africa, which was dated to an age between 1.8 and 1.5 million years. This fossil shares morphological traits with the early African Homo erectus , sometimes known as Homo ergaster .
