Early Upper Palaeolithic Pitfalls in the south foot of Mt.Fuji area

a0186568_22394517.jpgIt was in 1986 at Hatsunegahara Loc.B-1 site in Mishima City, Shizuoka Pref. 4 pits were uncovered beneath wide distributed tephra from Aira caldera in south- western Japan (A-Tn: 28.59±0.7cal kyr BP: Aoki et al.2008).
A scond discovery was in 1988 at Hatsunegahara Loc.A-2. 9 pits were uncovered from same layer as well as former discoveries. And it seemed arch-line distributed. After 47 pits were uncovered for the moment. Those pits are distributed crossing a narrow ridge like as blocking a pass on a ridge.

Nowadays, these pits are popular on EUP lavels in this area. So many pits are uncovered. They are usually distributed crossing a narrow ridge. Some scholaras claim that these characteristic distribution indicates trap-pit hunting. Recently Prof.Hiroyuki Sato (The Univ.of Tokyo) reviews in 'Late Pleistocene trap-pit hunting in the Japanese Archipelago',Quaternary Internationl, in press, doi:10.1016/j.quaint.2010.11.026
If you are interested with this, please participate in our dual symposia, 4th APA and Modern Human Behaviour symposium. This time, we; organizing comittee are planning short trip to this area. Unfortunately there will be no opened excavation. But you can touch geographical context and landscaepe. Also we will provide a brief presentation with rich pictures. We will discuss their condition and significance.
