Late Pleistocene and Holocene Palaeovegetational Changes at Alero El Puesto (AEP-1) Archaeological Site in the Northern Deseado Massif. Regional Palaeoenvironmental Implications and Early Human Occupation

The Southern Hemisphere SHCal04 radiocarbon calibration curve has been updated with the addition of new data sets extending measurements to 2145 cal BP and including the ANSTO Younger Dryas Huon pine data set. Outside the range of measured data, the curve is based upon the ern Hemisphere data sets as presented in IntCal13, with an interhemispheric offset averaging 43 ± 23 yr modeled by an autoregressive process to represent the short-term correlations in the offset.
