Kabuh Formation

The Kabuh Formation is a Plio-Pleistocene geologic formation from Central Java, consisting of several unnamed members belonging to the Kendeng Group.[1] Many of the fossils discovered from Sambungmacan belonging to this group were discovered in an accumulated sediment deposit in a flood-controlling canal near the Solo River, including a series of hominin crania that are similar in anatomy and geologically younger than the Ngandong hominins upstream. This area was excavated throughout the 1970s.[2][3][4][5][6]
