In September 1977,part of a well-fossilized tibial shaft of man was found together with faunal remains from the Solo River short-cut canal site at Sambungmacan in Central Java, Indonesia. The sediments exposed at the site have been tentatively divided into 4 units; Unit-Sbl, Unit-Sb2,Unit-Sb3 (late Pleistocene terrace deposits) and Unit-Sb4 (recent alluvial deposits) in ascending order : Unit-Sb1 and Unit-Sb2 have been inferred to be correlative with the Kalibeng and the Kabuh Formation in the Sangiran area respectively. While the exact findspot of the human tibia (surface discovery) in the field is unknown, the fluorine content of this specimen compares well with those of vertebrate bones in situ from the basal to the lower part of Unit-Sb2. Provided that the tibia derives from this Kabuh equivalent, it should be comparable in ago to early Javanese fossil hominids. However, some other layers are still possible for the source of the tibia. Further stratigraphic and chronological investigations are required to clarify the provenances of the Sambungmacan hominid remains including the calotte found in 1973 with characteristics of Solo man skulls.
