Abstract: A lot of archeological remains including one tooth of late Homo sapiens, used fires remains, several hundreds of stone artifacts, a few bone artifacts and some animal fossils of modern species were found in the Dabanqiao Cave site. The cultural level is 2 meters thick, and its upper part was dated to be 8175±235 B. P. and 8215±235 B.P. , its middle part was dated to be 10530±280 B. P. by 14C dating.
The raw materials of the artifacts are mainly quartz and crystal. The principle flaking method is the bipolar technique. The tool including scraper only is mainly made on flakes, re-touchcd roughly, and rregular in shape. Percussion method and bipolar technique were used tore touch. A bone aw1 carefully polished was found in the site. The evidence mentioned above indicates that this is a special culture not found before in Yunnan, so, it is named "Dabanqiao Culture". These remains are different from those found in Yunnan and southeast Asia before,and are somewhat similar to those found in Fulin and the upper part of Ma'anshan site. If, on the consideration that bipolar technique was mainly used to flake,Dabanqiao Culture is morcsimilar to the Cluture of Sinanthropus and. Xiaonanhai, which are more carlier than it. Consequcntly, it can be said that Dabanqiao Culture is probally in closer relation to the paleolithic cultures of North China than to Fulin and Ma’anshan. But it could not be excluded that this is a coincidencc of regional culture.
From the study of animal fossils and spores, it is shown that Dabanqiao site is in thesubtropical context, in which there arc hilly lands and flat lands. Lots of spores of Pinus and some Compositae foumd in the lower part of the cultural level indicate that the climate is warm and a little dry and the spores of pteridophytc of which most are Pteris in the upper part indicate that the climate is damp and hot.
