In September 1977 a geological survey was conducted under the Indonesia-Japan Joint Research Project CTA-41 (see Watanabe & Kadar [eds.]: Special Pub., No. 4, Geological Research & Development Center (GRDC), Bandung, 1985) at the Solo River short-cut canal site near Sambungmacan, where a skull of Solo man type was discovered in 1973. A well-fossilized shaft fragment of human tibia has been recognized among vertebrate bones collected during this 1977 fieldwork and stored in GRDC.The sediments exposed at the site consist of 4 units; Unit-Sbl(correlative with the Kalibeng Formation), Unit-Sb2(cor. with the Kabuh Formation), Uint- Sb3(late Pleistocene terrace deposits) and Unit-Sb4(recent alluvial deposits) in ascending order (Indonesia-Japan Joint Study Team: GRDC, 1989). While the exact findspot of the tibia specimen (surface find) is unknown, the degree of fossilization (macroscopic view) and the fluorine content of the specimen compare well with those of bones from the lower to the basal part of the Kabuh equivalent at the site. Provided that the tibia derives from these parts of strata, it should be comparable in age to early Javanese hominids such as pithecanthropines.Further stratigraphic and chronological investigations are required to clarify the provenances of the Sambungmacan hominid specimens.

1977 年 9 月，印尼-日本联合研究项目 CTA-41（参见 Watanabe 和 Kadar [eds.]：Special Pub.，第 4 期，地质研究与发展中心 (GRDC)，万隆，1985 年）在 Sambungmacan 附近的梭罗河短截运河遗址进行了地质调查，1973 年在那里发现了梭罗人类型的头骨。 胫骨已被确认为 1977 年野外工作期间收集并储存在 GRDC 的脊椎动物骨骼之一。现场暴露的沉积物由 4 个单元组成；按升序排列为Unit-Sbl（与Kalibeng 组相关）、Unit-Sb2（与Kabuh 组相关）、Uint-Sb3（晚更新世阶地沉积）和Unit-Sb4（近代冲积沉积）（印度尼西亚-日本联合研究小组：GRDC，1989）。虽然胫骨标本的确切发现地点（表面发现）尚不清楚，但标本的石化程度（宏观视图）和氟含量与现场 Kabuh 同等物的下部到基底部分的骨骼进行了很好的比较。如果胫骨源自这些地层部分，那么它的年龄应该与早期爪哇原始人类（例如猿人）相当。需要进一步的地层学和年代学研究来澄清 Sambungmacan 原始人类标本的来源。
