Observations

Most of the facial skeleton of the fossil is missing. Only the Neurocranium is in a fairly complete state. Researchers have calculated that the fossil is about 1.6 million years old and likely represents a male.[2] KNM ER 3883 is a more robust and a little larger than KNM ER 3733.[3] The cranium is long and low and it has postorbital construction. 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]
