Resumen:
The central region of Argentina, especially Córdobaprovince, has been the subject of numerous bioarchaeological andarchaeobotanical studies over recent years. However, the available informationrelated to plant use has been mainly obtained in populations that inhabited theCentral Highlands, while for the Eastern Lowlands little information is known,with various aspects related to the consumption and / or manipulation of thevarious plant resources present in the area still needing elucidation. In thiscontext, the objective of this work was to address for the first time theconsumption and management of plant resources by the populations that inhabitedthe southern coast of the Mar Chiquita lake of the Eastern Lowlands in the lateHolocene, through the analysis of vegetable microremains contained in dentalcalculus. The dental calculus present in 11 individuals from El Diquecitoarchaeological site was analysed and dated by AMS at between 2562 ± 47 and 537± 57 14C years BP, of which isotopic data (δ13Ccol) are also available. Ourresults revealed that the consumption and/or manipulation of wild plantresources, such as Geoffroea decorticans and Prosopis sp., and for the firsttime, of Trithrinax campestris, took place throughout the late Holocene.Related to this, there is no previous evidence of its management in either theCentral Highlands or Eastern lowlands. The incorporation of cultivated plantswas shown to have occurred at around 1200 years BP with the presence ofPhaseolus sp. and Zea mays (Poaceae), which was followed later by Cucurbita sp.However, the practice of horticulture did not replace the hunting and gatheringstrategies previously identified.
