'Alien' Skulls: Deformed Craniums Discovered In 1,000 Year Old Mexican Cemetery

Excavation of an ancient burial site in South Sonora, Mexico, has revealed a series of skeletons with intentionally deformed skulls.

Of the 25 sets of human remains found close to the Mexican village of Onavas, 13 had deformed craniums and five had evidence of dental mutilation.

According to Past Horizons, misshapen skulls have not been recorded before in the Sonora cultural groups, although they are documented among Mesoamerican peoples.

The process of elongating a skull usually begins in childhood with a process called “cradle-boarding”.

Ryan Matthews of Science Channel series Oddities told HuffPost Weird: “They would put two boards around the head and wrap it very securely. Because the head of a child is very soft, it can be manipulated forward, but the process would take several months.”
