Paleoenvironment and anthracology: determination of variations in humidity based on anatomical characters in archealogical plant charcoal (Ambato Valley, Catamarca, Argentina)

Anatomical features related to water deficiency were analyzed in archaeological plant charcoal as a paleoenvironmental indicator. The end of the Aguada settlements in the Valley of Ambato (Catamarca, Argentina), which took place towards the end of the first millennium of this era, was used as the case study. Tools from Ecological Anatomy were applied to recreate paleoenvironmental scenery for the studied processes. The results of the analyses showed that this area must have been undergoing a period of arid conditions during the studied period.
