Direct dating of human fossils
His team soon excavated a molar (Trinil 1) and a skullcap (Trinil 2).
Believing that the three fossils belonged to a single individual, "probably a very aged female", Dubois renamed the specimen Anthropopithecus erectus.
Some dismissed the fossils as apes and others as modern humans, whereas many scientists considered Java Man as a primitive side branch of evolution not related to modern humans at all.
In the 1930s Dubois made the claim that Pithecanthropus was built like a "giant gibbon", a much misinterpreted attempt by Dubois to prove that it was the "missing link".
After the discovery of Java Man, Berlin-born paleontologist G. Between 19 von Koenigswald discovered fossils of Solo Man from sites along the Bengawan Solo River on Java, including several skullcaps and cranial fragments.
Considering the Mojokerto child skull cap to be a closely related to humans, von Koenigswald wanted to name it Pithecanthropus modjokertensis (after Dubois's specimen), but Dubois protested that Pithecanthropus was not a human but an "ape-man".Other fossils found in the first half of the twentieth century in Java at Sangiran and Mojokerto, all older than those found by Dubois, are also considered part of the species Homo erectus.
