>Over two seasons of excavations, INAH archaeologists collected 180 mostly complete skulls from the tower as well as thousands of skull fragments. Now, those finds sit in a lab next to the Templo Mayor ruins, being painstakingly examined by a team led by INAH anthropologist Jorge Gómez Valdés. Cut marks on the skulls leave no doubt they were defleshed after death, and the decapitation technique appears clean and uniform. "[Mexica priests] had extremely impressive anatomical knowledge, which was passed down from generation to generation," Chávez Balderas says.
