MEXICO CITY, MEXICO—More than 140 pots containing cremated human remains have been found at the 700-year-old site of Cerro de Trincheras, by researchers from Mexico’s National Institute of Anthropology and History. The pots, some of which were shaped as pumpkins, ovals, or with long necks, also held incinerated rock beads, crystal quartz, and jewelry. The team, led by archaeologist Elisa Villalpando Canchola, found two cremation pits and the location of a pyre that had been placed on the ground, the bones of animals, and pottery bowls.
