The Locality 1 hominins, which show relatively little morphological variation, resemble, but are not identical to, the P. erectus remains recovered from Java.
In 1936, Ralph von Koenigswald's exploration of the Sangiran Dome recovered the first of many P. erectus remains, but the search for fossils was curtailed in 1940 because of WWII. Since the end of WWII researchers operating in and around the Sangiran Dome have recovered crania, mandibles and some postcranial remains.24 Many researchers assign the Homo (Javanthropus) soloensis remains from Ngandong, Indonesia, to what we now call H. erectus. The other major contribution to the hypodigm comes from the Sinanthropus pekinensis fossils from Locality 1 at the Zhoukoudian (formerly Choukoutien) Cave near Beijing. The Locality 1 hominins, which show relatively little morphological variation, resemble, but are not identical to, the P. erectus remains recovered from Java. Subsequently, similar-looking evidence has come from sites in Africa and Eurasia.
