A site on the Grijalva River in Chiapas, Mexico, with one of the longest occupational sequences in Mesoamerica, c 1500 BC to the present. It flourished in Late Pre-Classic to Early Classic times with adobe construction, ceramics and figurines, and then pyramids dating to 550 BC and residential complexes of cut stone to 150 BC. The style and iconography of certain artifacts indicate contact with Izapa and Kaminaijuyu in the Late Pre-Classic. Hundreds of broken sherds tell of trade contact with sites in the Penen, Monte Alban, and Teotihuacan in the Early Classic.
