Sample aka: La María Quebrada
Reference: R. Paunero, C. V. Davis, D. Rindel, and A. Tessone. 2017. La fauna pleistocénica: evidencias zooarqueológicos en la Meseta Central de Santa Cruz, los sitios de La María. Magallania 45(2):181-198 [ER 3387]
Geography
Country: Argentina
State: Santa Cruz
Coordinate: 48° 24' S, 68° 52' W
Coordinate basis: estimated from map
Time interval: Holocene
Max Ma: 0.01051
Min Ma: 0.0104
Age basis: radiocarbon (uncalibrated)
Geography comments: coordinate estimated based on photo in Fig. 1
there are uncalibrated 14C dates on bone of 10420 +/- 180 ybp and 10510 +/- 100 ybp (unit 8) and 10400 +/- 59 ybp and 10408 +/- 100 ybp (underlying unit 10)
the dates are interpreted as falling in the Pleistocene/Holocene transition, but the two-sigma ranges of the calibrated dates are all less than 10516 ybp, so the interval is entirely early Holocene
