c. 270 BC: The El Convento site in northern Puerto Rico has provided the earliest radiocarbon assay for the Huecoid manifestation in the region. This early date challenges the traditional model of a slow east-to-west movement of these groups along the island’s northern coast. Similarly, at the Maisabel site, Huecoid ceramics were discovered in a sealed stratum located directly beneath Hacienda Grande (Saladoid) deposits. These findings suggest that the Huecoid culture may have been established in certain parts of Puerto Rico earlier than in eastern sites like La Hueca. Such chronological data is essential for refining the migration maps of the first ceramic-producing societies in the Caribbean.
