While similarly well-preserved Late Pleistocene cave sites are found in other regions of the world, the cave sites in this region of South China (as well as several sites in neighboring Japan and the Russian Far East) are unique due to the presence of ceramic vessels in their otherwise Late Paleolithic assemblages.

Among the well-known sites in China from this period are Xianrendong and Diaotonghuan in Jiangxi Province (1–15), indicating that the world's first pottery was produced in East Asia.

The Terminal Pleistocene warming was interrupted by the Younger Dryas ca. Although the Younger Dryas is seen in other regions as a generally cold and dry period, in South China the main effect of the Younger Dryas was probably the sudden onset of greater seasonality.

Understanding the local impact of the Younger Dryas on the basin of the Yangzi River and in particular in the limestone region south of the main river channel is still not possible (20).

A taxonomic and taphonomic study of the fauna was also carried out (26).

The small collection of lithic artifacts recovered was recently recorded and found to reflect the same tool categories, dominated by core-choppers and retouched flakes, known from the first excavations.

Here we report on the radiocarbon ages of the sediments based on analyses of charcoal and bone collagen.

First, the complex deposition of interdigitating lenses of ashes, clays, and sometimes fine gravel requires systematic dating based on a series of radiocarbon determinations and this has been lacking.

Charcoal and bone collagen samples located above and below one of the fragments produced dates of around 18,000.

These ceramic potsherds therefore provide some of the earliest evidence for pottery making in China.

The cave was first excavated in 19 by one of the authors (J.

Y.), who uncovered 2 clusters of potsherds indicating the presence of 2 vessels (Fig. A piece of charcoal closely associated with the potsherds was dated to 16,700–15,850 cal BP and organic residue from the ceramic to 17,750–16,900 cal BP (7, 16, 17, 25;) (Table 1).
