MEXICO CITY, MEXICO—In the Mexican state of Jalisco, archaeologists are unearthing the remains of 23 ceremonial structures at the site of Teocaltitan. Erected during the Classic period, between 450 and 900 A.D., the buildings are similar in style to ones still standing at the famous ancient city of Teotihuacan. Archaeologist Marisol Montejano Esquivias is heading the National Institute of Anthropology and History team excavating the site. “The interesting thing about Teocaltitan, apart from having Teotihuacan influence, is that it has elements that are very characteristic of the region such as the square architecture, sunken gardens in U-shape, pyramids with closed gardens, [and] ball game courts,” said Montejano. In one ball court, her team also found copper and shell earrings next to the cranium of a decapitated person. The artifacts date to between 900 and 1200 A.D., indicating the center was used in the Post Classic Period.
