Major Classic Maya site on the Usumacinta River, Chiapas, Mexico. It has architectural features like Palenque, hieroglyphic inscriptions on stone lintels and stelae, and monuments depict war. Though there are a number of structures, including palaces with ornamented stucco roof-combs and mansard roofing, temple-pyramids, and two ball courts, the site is best known for its more than 125 carved lintels. It flourished c 600-900 AD. Though the site may have been controlled briefly by the Putun just before 750, it was finally abandoned during the general Lowland Maya collapse.
