KNM ER 3883
KNM ER 3883 is the catalogue number of a fossilized skull (nearly complete cranium) of the species ''Homo erectus''. The fossil was discovered by Richard Leakey in 1976 in Koobi Fora, east of Lake Turkana (formerly lake Rudolf), Kenya.〔(【引用サイトリンク】url=http://www.efossils.org/page/boneviewer/Homo%20ergaster/KNM-ER%203883#100478266 )〕 == 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.〔(【引用サイトリンク】url=http://humanorigins.si.edu/evidence/human-fossils/fossils/knm-er-3883 )〕 KNM ER 3883 is a more robust and a little larger than KNM ER 3733. The cranium is long and low and it has postorbital construction. It has a large face and zygomatic bone.〔 Shows a cranial capacity greater than any previous hominid capacity which is estimated at 804 ml.〔(【引用サイトリンク】url=http://web.mesacc.edu/dept/d10/asb/origins/koobi/knm3883.html )〕
