Ancient cubed-shaped skull found in Mexico challenges human history

An ancient cube-shaped skull unearthed in Mexico is rewriting our understanding of the ancient world, revealing a completely unique member of a society from 1,400 years ago.

This remarkable skull belonged to a man over 40 years old who lived during Mexico's Classic period, roughly between 400 and 900 AD, according to specialists from the National Institute of Anthropology and History (INAH).

It was discovered at the Balcón de Montezuma archaeological site in the mountainous northern Huasteca region of Mexico's Tamaulipas state.

Researchers determined through bone and teeth analysis that the man was born, lived his entire life, and died right there in the local mountains, with no evidence he ever moved or lived in another region.

The team added that the find was 'unprecedented' in this part of the world as a skull deformed to resemble a cube had never been found near Huasteca before.

The skull's unique appearance was the result of intentional cranial deformation, a practice where flat boards and bandages were pressed against a baby's soft head for years to mold it into a square shape.

This deformation was likely done without causing pain, as the skull bones of an infant are malleable, allowing families to gradually reshape the head as a cultural tradition.

Experts believe such rituals were performed to signify beauty, social status, or even spiritual connections in ancient Mesoamerican societies.

Archaeologists have previously uncovered a variety of intentionally modified skulls across ancient Mexico, particularly elongated cone-like shapes among the Olmec and Maya.

Those cone-shaped skull changes are believed to have been achieved by gently binding infants' soft heads with cloth and bandages during the first months or years of their lives.

To the ancient Mesoamericans, these oddly-shaped skulls held a different significance depending on the ancient civilization making the changes to their babies. For example, the ancient Maya are believed to have done this for social status and beauty.

However, the newly discovered cube skull has left researchers with a mystery, as the team from INAH could not explain why this man was the only human to undergo this procedure in Tamaulipas.

Cube-shaped skulls, with their flattened tops that create a boxy profile, have typically been found at distant sites like El Zapotal in Veracruz and scattered Maya settlements in southeastern Mexico, far from the northern mountains where this fossil turned up.

With that in mind, the research team decided to test if the 40-year-old was truly a native of the northern Huasteca region.

Scientists looked at specific clues hidden in his bones and teeth. These clues are called 'stable oxygen isotopes,' or different versions of oxygen atoms that don't change over time.

The exact mix of these oxygen versions in bones and teeth come from the water a person drinks throughout their life.

The research team was able to confirm that this man spent his entire life in the region, making his cube-shaped skull more of a mystery since this ritual was unusual for the area

Water in different places, such as in rainy mountains or dry coasts, has its own unique oxygen 'fingerprint' because of the local climate and geography.

By testing those oxygen fingerprints in the man's tooth enamel, which formed in childhood, and bone collagen, which updates through adulthood, researchers saw the same mountain water pattern in both.

That made it a match for the local mountain water this person likely drank his whole life in Mexico's northern mountains.

Physical anthropologist Jesús Ernesto Velasco González said: 'Stable oxygen isotope studies in collagen and bioapatite samples from bone and teeth, a technique used to infer the geographic origin of the second individual's skeletal remains, indicate that he was born, lived, and died in this part of the mountains.'

'Therefore, the results rule out a direct mobility relationship with the groups of El Zapotal or those further south,' the researcher continued in a statement translated to English.

While the team is still trying to crack the mystery behind the cube-shaped skull, they said it likely wasn't just about looking different, but may have been a symbol of belonging to a larger cultural family that stretched across hundreds of miles of Mexican coastline.
