Observations
KNM-ER 3883 is a significant fossil specimen of early African Homo erectus, dating to approximately 1.5–1.6 million years ago. This cranium, discovered in Kenya, has an endocranial volume exceeding 800 cc, which is substantially larger than earlier Homo species and suggests a notable increase in brain size.[2][3] The cranium is long and low and it has postorbital constriction. It has a large face and zygomatic bone.[1] It shows a cranial capacity greater than any previous hominid capacity which is estimated at 804 ml.[4]
