Orígenes 13 -Secuencia cronoestratigrafica de Urupez II. Nuevas dataciones radiometricas

– Chronostratigraphical sequence in URUPEZ II. New radiometric dates. Three new C 14 dates have been obtained from charcoal samples of the archeological site URUPEZ II, Uruguay. Two samples dated 10.800 years before present by AMS radiocarbon dating, and the third 12.000 years before present, which corroborates the Pleistocene-Holocene transition age of the site, and the posibility of an older antiquiety. Using the same method previous samples were dated 10.690 and 11.690 years before present (MENEGHIN, 2004, 2006).
