-Mandibular fossa morphology- Ngandong 6 was found to have an unusual morphology of the mandibular fossa. Many fossils were examined in order to understand it's rear morphology. Ng12 (Solo XI)was a key specimen in the search for answers because this specimen was found to be intact and preserved. A lack of inferior projection of the squamosal temporal is a key difference Ngandong fossils and other modern human fossils. Although Ng6 (solo V) fossil only preserves the left mandibular fossa, it also exhibits the same mandibular characteristics of Ng12 (solo XI). The fossil of Ng 6 shows to have a strongly developed ridge on the anterior wall of the fossa while the squamosal temporal slopes towards the STF. Groundwork evidence from Westaway and colleagues (2007) supports that Ngandong hominids went extinct approximately 126 kyr and it's highly suggested that these hominins went extinct before contributing to the modern human gene pool. This evidence suggests that hominins found in Indonesia and modern humans are rare to modern humans found in Australasia.

-The Discovery of Ngandong man- Ngandong man is described by Santa Luca (1980) as a late variety of Homo erectus on Java. Its cranial capacity was approximately 1100-1200 cc, with a robust supraorbital angle and occipital tori. The appearance of the Tidiae appeared to be modern in form. These findings confirm what had already been highlighted by other researchers, Ngandong man had many similarities to the early Homo erectus.
