RECONSTRUCTING THE ANCIENT ENVIRONMENT AT YAXNOHCAH, CAMPECHE, MEXICO: A MULTI-PROXY STUDY

The Ancient Maya city of Yaxnohcah reached its apogee in the Preclassic period (800 BCE – 200 CE) but continued as a large settlement through the ensuing Classic period (200 -800 CE). We analyzed several types of paleoenvironmental proxies from various contexts, including ancient reservoir sediments and buried soil surfaces in an attempt to understand landscape changes associated with Maya urbanism at Yaxnohcah. Our analyses included ancient pollen, macrobotanical remains, eDNA, soil geochemistry, and Carbon isotopes. Resulting data often complimented each other allowing us to reconstruct a fuller picture of the changing landscape across space and time at Yaxnohcah. Results from eDNA analysis offer unique insights not found in the other proxies and offer a promising new avenue in environmental archaeology in the Maya Lowlands.
