image: Two mandibles of Homo erectus which date to between ca. 0.90 and 1.1 million years ago. These specimens [left, Pithecanthropus C (Sangiran 9); right, Pithecanthropus F (Sangiran 22)] belong to the chronologically older group of the Sangiran hominins. It is interesting that the mandibles have been reported to display relatively primitive features which are comparable in morphology to hundreds of thousands of years earlier African Homo erectus. This material relates to a paper that appeared in the Jan. 10 issue of Science, published by AAAS. The paper, by S. Matsu'ura at National Museum of Nature and Science in Ibaraki, Japan, and colleagues was titled, "Age control of the first appearance datum for Javanese Homo erectus in the Sangiran area." view more
