More than 150 skulls have been found in a drained lake near Mexico, complete with vertebra attached. Archaeologists are hypothesizing that they may have been victims of a mass sacrifice.
Carbon dating suggested that the skulls were at least 1,100 years old, and the few dozen analyzed so far are mostly from men, Morehart told LiveScience. The researchers did not release photos of the skulls because the sacrifice victims may have historic ties to modern-day indigenous cultures.
The findings shake up existing notions of the culture of the day, because the site is not associated with Teotihuacan or other regional powers, said Destiny Crider, an archaeologist at Luther College in Iowa, who was not involved in the study.
