CRS Vietnam Field Trip Report THE ACTIVITY OF THE EXCAVATION IN THE BAU DOU SITE

Overview

The Bau Do site had been excavated from 25th February to 25th March by the Archaeology Center, and the expert team consisted of members of the Australian National University and Sapporo Medical University of Japan. Fortunately, we had the opportunity to take part in this excavation and survey for three days (6th May-8th May). This site is important as it is one of the first research to investigate piled shell midden Neolithic site in this area, and I had the great opportunity to explore the Southeast Asian archeological site which is located near the ocean.

 

1. Site Setting

   Bau Du site is located in But Dong village at Tam Xuan commune in Tam Ky district in Quang Nam province. Almost of this site is a shell midden site on the mound surrounded rice field. There are two trenchs in the site, both of them are 2×5 m square and more than1.5 m in depth. It is said that this site has Neolithic layer belonging to around 6000B.P, and Sa Huỳnh culture layer around 3000 B.P on the upper side of this layer. Thus there is a gap between the Neolithic cultural layer and Iron age one for residence.

2. History of Research

              In 1981 Bau Du site was founded first, but in 1983 an excavation was carried out. A noteworthy discovery was a resent excavation done in 2014. During this excavation, two skulls were discovered and which dated back to 5000-6000 years ago. Other artifact were also found during this discovery.

3. Our activities

 3.1 Planning the map

         One of our main activities was to survey this site using Totalstation which is one of survey instruments. This contour map was used as the sample for researching the site location using. We had to consider about the shape of the land and measure it using the contour (Fig.1). Then we recorded the position and the height which we set Totalstation ourselves and using automatic memorizing for Totalstation, however this method increased the likelihood of mistakes being made it easy to mistake. That is one point we have review.

3.2 Excavation

              During a team survey, another team joined the excavation. The only remains we could find were lithics and shell midden, as well as some human bones (Fig2-4). It is said that these stone tools are dated back to the Neolithic period. While the only chipped stones I could see were flakes or blades, no tools were found. Although I wanted to observe the artifacts in more detail, we didn’t have enough time. Professor Zun explained there might be a chance of finding artifacts in the lower layer than the shell midden.
