Chiapa de Corzo (Mesoamerican site)

[2][3] In 2008, archaeologists discovered a massive Middle Formative Olmec axe deposit at the base of Chiapa de Corzo's Mound 11 pyramid.

[8] The site is believed to have been settled by Mixe–Zoquean speakers, bearers of the Olmec culture that populated the Gulf and Pacific Coasts of southern Mexico.

Chiapa de Corzo and a half dozen other western Depression centers appear to have coalesced into a distinct Zoque civilization by 700 BCE, an archaeological culture that became the conduit between late Gulf Olmec society and the early Maya.

[9][10][11] Certain Mesoamerican traits such as planned cities, earthen pyramids, E-Group commemorative complexes, cloudy-resist waxy pottery, incensarios, and early logographic writing may have originated in the Zoque region.

[12] Chiapa de Corzo and a number of western Depression sites were abandoned by the Late Classic period, a population change that closely coincides with the invasion of a war like group of Manguean-speaking people known as the Chiapanec.

[15][16][17] The Chiapanec chose to occupy the adjacent floodplain of the Grijalva River where the modern town is now located, and they left the Zoque ruin on the nearby plateau untouched.

In recent years, the Instituto Nacional de Antropología e Historia (INAH) has purchased sections of the site from local land owners.

The site is currently under investigation by a collaborative team of researchers from Brigham Young University, INAH-Chiapas, and Mexico's UNAM (see http://chiapadecorzo.byu.edu/ Archived 2011-08-13 at the Wayback Machine).

Chiapa de Corzo has more clay cylinder seals and flat stamps than any other Formative Mesoamerican site, save Tlatilco.
