Photos: 25 Alien-like skulls discovered in ancient Mexican cemetery

ONAVAS, Mexico — A team of archaeologists recently stumbled upon a group of 25 alien-like skulls in a small Mexican village just outside of Mexico City that date back 1,000 years ago.

According to the Medical Daily, those archaeologists said 13 of the 25 ancient skulls show evidence of cranial deformations known as “head binding.” They were discovered in an ancient cemetery near the town of Onavas.

Head binding was an intentional practice that likely distinguished a degree of rank for the individuals whose skulls were discovered, according to the Medical Daily. The earliest evidence of cranial deformations dates back to about 400 BC.

These particular skulls date back to the year 953 AD, according to the archaeologists who discovered them.

Judging from the discovered skulls’ appearance, archaeologists believe two boards were used to apply pressure to both sides of their heads at a very young age. That practice was likely continued for a number of months for it to become permanent.
