Short summary
The Llanos de Moxos (Bolivian Amazon) host thousands of anthropogenic forest islands from the Holocene. These sites contain shell middens primarily composed of freshwater snails (Pomacea spp.), often used for ¹⁴C dating. To evaluate potential radiocarbon reservoir effects (RRE), modern Pomacea shells and coeval tree leaves were analysed. Results reveal no significant RRE, supporting their reliability for dating archaeological and paleoecological records in the region.
