Geography
Country: China

State: Guizhou


Coordinate: 28° 8' N, 106° 50' E
Coordinate basis: based on nearby landmark

Time interval: Late Pleistocene

Section: 3225

Unit number: 1

Unit order: above to below

Max Ma: 0.031155

Min Ma: 0.019295

Age basis: radiocarbon (uncalibrated)

Geography comments: "2 km southeast of Tongzi County" (basis of coordinate)
there are four 14C dates and U-series date on layers 3-6, ranging from 31,155 +/- 140 BP to 19,295 +/- 65 BP; there is an additional, imprecise date of 15,100 +/- 1500 that the authors appear to discount (presumed to be uncalibrated because errors are symmetrically distributed)

Environment
Lithology: claystone

Taphonomic context: cave,human accumulation

Archaeology: stone tools

Habitat comments: the upper part of the sequence is strata 1-6, consisting of "Argillaceous clay with scattered breccias", but only fossils from strata 3-6 are reported
there are many "stone artifacts" but no ceramics
there are numerous cut marks and "hominins were the primary agents of bone collection and modification at the site"

Methods
Life forms: carnivores,primates,rodents,ungulates,other small mammals,birds

Sampling methods: quarry

Sample size: 2889 specimens

Sampled by: S. Zhang, F. Long

Years: 1986, 1990

Sampling comments: "Sieving was not performed during the excavations, but much effort was made to collect all of the lithic and faunal fragments from the excavated sediments... the excavators used another method called patting collection"
