Pomoná is a site that dates from the Early Classic (500 - 800 C.E.), and it lies in the valley of the Usumacinta River as it jogs into the state of Tabasco. Recent archaeological explorations have uncovered six buildings for viewing. It is one of the settlements for which an emblem glyph, indicating its role as one of the main sites in the region, has been identified. Without doubt the site had connections with such city-states as Yaxchilán, whose chieftain Jaguar Bird is depicted on a tablet at Pomona. There also is evidence from a stelae, dated 795 C.E. at Piedras Negras that connects Pomoná to Yaxchilán.
