Usumacinta Style 550 - 850 C.E.
or the Mid Classic period.
Another derivative of the Peten style, Usumacinta styles are found in large cities in the valley of the Usumacinta river that boarders between Mexico and Guatemala. Examples of this style can be found in Yaxchilan, Palenque and Piedras Negras and in some instances Bonampek. The most distinctive characteristic used in this geographical area are the outward inclination of the roof of buildings, the use of open roof combs with geometric designs and the decoration of piers, interior walls and roof panels with masks and human figures. Lintels are also carved with dates, the lineage of city rulers and special events.
