SAN ANTONIO - More than a dozen mutant skulls have been discovered in Mexico.
Archaeologists found skeletons in a pre-Hispanic burial ground in the state of Sonora. The skeletons all have a distinct feature - signs of skull binding.
The ancient practice was performed on Meso-American youth as a rite of passage into adulthood. It is believed the tradition may have killed many people. Some of the skeletons also had indications of deformed teeth.
The discovery reveals the reach of ancient Meso-American cultures was wider than first thought.
