Relocation of the 1936 Mojokerto skull discovery site near Perning, East Javathe southern margin of a topographic nose at the upper end of a c.18 m-wide gully (c.0663760 m E, 9183430 m N, UTM Zone 49M), c.15 m SE of the Kumai cs (1985) re-location.

The fossil calvaria of "the Mojokerto child" was discovered in 1936, but uncertainties have persisted about its paleo-environmental context & geological age because of difficulties in relocating the discovery site.
Past relocation efforts were hindered by
- inaccuracies in old base maps,
- intensive post-1930s agricultural terracing,
- new tree & brush growth.
Fortunately, geologic cross-sections & site photographs (1936-1938, not fully utilized in past relocation fieldwork) closely circumscribe site geography & geology. These documents match the conditions at just 1 sand-stone outcrop. It is situated on
The relocated discovery bed is c.3.3 m of fossiliferous pebbly sand-stone, a river-channel deposit cut into tuffaceous mud-stone. The sand- & mud-stone beds correspond to original site descriptions. Pebbly sand-stone is also found within the skull. Thecalvaria is well-preserved, taphonomically similar to large & fragile spms found among several 100 vertebrate fossils excavated from the sandstone in 2001-2002. Since no well-preserved fossils were found intact at the surface of the sandstone, the good
The relocated hominin bed is the uppermost fluvial sandstone of a marine-deltaic sequence in the upper-Pucangan Fm. The Mojokerto child probably died along the ancient sea-coast, judging from
- the large extent of the deltaic facies &
- evidence that the calvaria experienced minimal transport.
The relocated discovery bed is c.20 m stratigraphically above the horizon from which the widely cited 1.81 +-0.04 Ma 40/39Ar date for the skull (Swisher cs 1994) was obtained.
Additional field & laboratory results will be required to determine the skull’s age.
