In 1977 a hominid tibial fragment (Sm 2) was collected (not in situ), together with other overtebrate bones, from sambungmacan. The bone has heen inferred to be derived from the Kabuh equivalent layer. The fragment is a lower shaft of the right tibia, black in colour and well-fossilized. The total length was estimated as about 37cm, comparable to that of Solo B. In diameters (32.0mm and 21.2mm) and flatness (66.3) of the mid-shaft, it is close to East Asian Neolithic males, apart from Solo A and B and Zhoukodian (Choukoutien), and completly different from European Neandertals and Upper Palaeolithic Sapiens. However, the cortex is extremely thick and the medullary cabity is very narrow, resembling the condition of the limb bones from Zhoukoudian. As a whole, this tibial fragment shows rather advanced character in spite of its old chronological age.
