content: Brown skull cast of KNM-ER 1813. This skull cast represents one of the most complete skulls of this species (Homo habilis), best known from the Turkana Basin (Kenya) and Olduvai Gorge (Tanzania) in East Africa. It has a cranial capacity of only 510 cubic centimeters, well below the 600 cubic centimeter cutoff that had been in place since the creation of the Homo habilis species name. It is also not much larger than the average for Australopithecus. Still, KNM-ER 1813 is similar to many of the accepted Homo habilis specimens from Olduvai Gorge. The similarities include overall size, smaller orbits, and sub-nasal prognathism (projection of the face below the nose). It is somewhat skewed on its left side, a result of the pressures the skull experienced during the fossilization process. The third molars were fully erupted and showed evidence of wear, so she was probably a female who was fully mature at the time of her death. The real skull is about 1.9 million years old. The cast measures around 17 cm x 11.5 cm x 11 cm in size. Find out more by visiting humanorigins.si.edu
