Chacmools are a distinctive sculptural form associated with the Mesoamerican cities of Chichen Itza and Tula. A recently excavated sculpture found at Las Mercedes in Costa Rica, over 2000km to the south, closely resembles the Mesoamerican chacmools. Comparing this new chacmool-like sculpture with similar examples at the American Museum of Natural History and the National Museum of Costa Rica, the authors demonstrate that these sculptures were common in lower Central America, and propose a connection between Central America and Mesoamerica dating back to AD 1000. They interpret the Costa Rican chacmools as ritual furniture employed by local chiefs to enhance their power and prestige through the enactment of Mesoamerican-inspired rituals.

Detailed analysis of the animal bone assemblage at Gola Dhoro here throws light on the expansion of the Indus civilisation into Gujarat. A square fort, imposed on a settlement of livestock herders in the later third millennium BC, was shown to have contained people who introduced a broader diet of meat and seafood, and new ways of preparing it. These social and dietary changes were coincident with a surge in craft and trade.
