Abstract


The first collagen AMS radiocarbon dates from the Camet Norte fossil site (Buenos Aires Province, Argentina) range from ca. 24,730±110 years 14C BP to 23,690±100 years 14C BP, or ca. 29,000 cal. BP to 27,600 cal. BP. The dates were obtained from specimens of the Level B of this fossil site. The age of the site fits well with the results of previous studies, but the more precise AMS radiocarbon dating allowed for a better determination of the site’s chronology. Models were used to better understand the chronological range of the investigated specimens.
