Known monuments

Seventeen confirmed examples are known. An additional monument, at Takalik Abaj in Guatemala, is a throne that may have been carved from a colossal head. This is the only known example outside of the Olmec heartland on the Gulf Coast of Mexico. Possible fragments of additional colossal heads have been recovered at San Lorenzo and at San Fernando in Tabasco. Crude colossal stone heads are also known in the Southern Maya area where they are associated with the potbelly style of sculpture. Although some arguments have been made that they are pre-Olmec, these latter monuments are generally believed to be influenced by the Olmec style of sculpture.
