Radiocarbon dating of fossils taken from caves on islands along
The cave became known as Red Deer Cave, because of the fossils of giant red deer subsequently excavated at the site.
But the most curious fossils discovered at the site appeared to be those of humans.
Their findings revealed that the bone resembles equivalent fossils belonging to some of the earliest known members of the , considered to be a more advanced species on the human evolution spectrum, and another revolutionary development, were first discovered by Eugene Dubois in 1891 on the island of Java in Indonesia.
Many other , the Maludong thigh bone is very small; the shaft is narrow, with the outer layer of the shaft (or cortex) very thin; the walls of the shaft are reinforced (or buttressed) in areas of high strain; the femur neck is long; and the place of muscle attachment for the primary flexor muscle of the hip is very large and faces significantly backwards."We published our findings on the skull bones first because we thought they'd be the most revealing, but we were amazed by our studies of the thigh bone, which showed it to be much more primitive than the skulls seem to be," Professor Ji said.
Archaeologists stored these fossils away and they remained unexamined for nearly two decades. That is, until 2008, when an international team consisting of scientists from Chinese and Australian institutions began to study them in earnest.
