First thing I thought of...
... was Richard Leaky's most famous skull find, known as KNM-ER 1470. Turns out 1470's head is too round in back. This looks more like the one in the article:
KNM-ER 3733, either H. erectus or H. ergaster
-- from TalkOrigins.org
I wish the article phil posted had mentioned a cranial volume...
