Specimen Data (Morphology)
KNM-ER 1813 has a cranial capacity of about 510cc which is smaller than the Olduvia Homos but just slightly larger than Australopithecines that have a cranial capacity between 440-485. The size issue was first looked at as sexual dimorphism but later when compared to KNM-ER 1470 another habilis it was clear that by comparisont KNM-ER 1470 was not a habilis and took on the new name of Homo rudolfensis. it also shares as do other hablili's the pronounced supraorbital torus along with a very robust zygomatic bone. KNM-ER 1813 also show some prognathic features in the maxilla portion of the face. Another feature of this specimen is that it has a crushed cranium that causes a distorted size of the cranial vault. KNM-ER 1813 does share similar features of specimen OH 24 in regards to pronounced supraorbital torus and prognathic maxilla.
