First Ams Radiocarbon Direct Dates on Bones from Extinct Megafauna in Camet Norte (Santa Clara Del Mar, Buenos Aires Province, Argentina)
(Asociacion Paleontologica Argentina, 2018-02)
The first AMS radiocarbon dates from the Camet Norte fossil site (Buenos Aires Province, Argentina) range from ca. 28,700 cal. BP to 27,500 cal. BP. The age of the site fits well with results of previous studies, but the ...
Aspartic acid racemization dating of Holocene brachiopods and bivalves from the southern Brazilian shelf, South Atlantic
(Elsevier B.V., 2006-09-01)
The extent of racemization of aspartic acid (Asp) has been used to estimate the ages of 9 shells of the epifaunal calcitic brachiopod Bouchardia rosea and 9 shells of the infaunal aragonitic bivalve Semele casali. Both ...

Radiocarbon reservoir ages and hardwater effect for the northeastern coastal waters of Argentina.
(University of Arizona. Department of Geosciences, 2008-12)
Accelerator mass spectrometry (AMS) radiocarbon dates were obtained for 18 mollusk shells collected alive along the Buenos Aires province coast, Argentina, over the period AD 1914–1935. Reservoir ages were estimated for ...

Dating the Peopling of Northwestern South America: An AMS Date from El Inga Site, Highland Ecuador
(Taylor & Francis, 2016-01)
The El Inga site in Ecuador produced an important number of fishtail (or Fell) points. Early 1960s conventional radiocarbon assays yielded dates ranging between 9000 and 4900 14C yr BP. Even the oldest one seems too young ...
Precise radiocarbon dating of Late-Glacial cooling in mid-latitude South America
(Academic Press Inc., 2003)
Variability of atmospheric 14C content often complicates radiocarbon-based chronologies; however, specific features such as periods of constant 14C age or steep changes in radiocarbon ages can be useful stratigraphic ...
Holocene evolution and geochronology of a semiarid fluvial system in the western slope of the Central Andes: AMS C-14 data in El Transito River Valley, Northern Chile
(Elsevier, 2017)
In this paper, we discriminate the contribution of the different sediment sources into a river situated in the semiarid region of northern Chile, differentiating the ones driven by the paraglacial response from the ones ...
