This is the first time that I heard about Bewah Cave. Bewah Cave is a limstone cave near Tasik Kenyir in Terengganu. It has fossil remains.
There was a human skeletal remains (replica) of a Bewah Cave inhabitant who was buried in foetal position, the legs were not straightened as with the Egyptian mummies.
The Bewah Cave dwellers were quite skilled and had used some of the most unique tools known in the history of man. Some of these tools were well formed (well made). They looked really good and functional.
