Geography
Country: China
State: Guangxi
Coordinate: 23° 25' 9" N, 107° 0' 0" E
Latlng basis: stated in text
Time interval: Middle Pleistocene
Max Ma: 0.2896
Min Ma: 0.242
Age basis: U/Th
Geography comments: "in the Bubing Basin"
three corrected U-series dates are given: the text implies that the majority of the fossils are from between a "lower flowstone" dated at 290.600 +/- 45 ka and 287.170 +/- 60 ka and a "middle flowstone" dated at 242.000 +/- 21 ka, and the "upper flowstone" is 14.190 +/- 4.200 ka
the uncorrected lower flowstone ages are treated as "robust maximum ages" but the corrected ones seem to be acceptable, so they are used here
