Last month, workmen building things in Argentina unearthed a skull that looked weird. This made stories about aliens and ancient mysteries spread like wildfire. The bones of a toddler who died at least 700 years ago looked a lot like the long-headed aliens who are sometimes depicted in science fiction. But archaeologists immediately put a stop to the idea that this skull came from another world. Instead, research indicated that changing the shape of the skull deliberately was a common and long-standing cultural practice. The discovery in San Fernando del Valle de Catamarca gives us a fascinating peek into how ancient cultures practically changed their kids’ heads to change their identities.
A Skull That Defied Expectations
The digging began as part of a normal water pipe project in northeastern Argentina. On May 27, workers found bones, including the very well-preserved skull of a child who was 3 to 4 years old. People immediately thought of “alien” pictures when they saw the skull’s flat, uneven shape, but experts quickly said it wasn’t an alien. Cristian Sebastián Melián, head of the Provincial Directorate of Anthropology in Catamarca, said that the distortion was a cultural practice called “oblique tabular” cranial alteration. People used this method to shape a child’s skull when they were very young.
The Science Behind Head Shaping

Gentle but steady pressure on a baby’s soft skull, often with cloth bindings, wooden boards, or padded devices, caused artificial cranial deformation. Different cultures had different ways of doing things. Some wanted heads that were longer, while others wanted heads that were flatter or sloped. In this case, the child’s skull had a very noticeable flattening at the front and back, which is a sign of the “oblique tabular” style. Researchers say that this practice, which seems extreme to us today, probably didn’t have much of an effect on health. Research shows that it was more about looks, social identity, or even spiritual beliefs than any medical need.
A Global Phenomenon with Deep Roots

Such practicing was not unique to a specific culture. From the Huns of Eurasia to the Maya of Mesoamerica, cranial modification was practiced almost universally. The Inca, who later settled in the region where the skull was discovered, practiced head shaping as well. Indeed, Melián’s team possesses over a hundred altered skulls, with roughly ninety percent exhibiting some form of deliberate modification. These practices are most famously associated with the Paracas and Mangbetu cultures with Peru and Africa respectively, who created stunningly elongated skulls and continue to be the subject of conspiracy theories to this day.
Why Did Ancient Societies Reshape Skulls?

The motivations underlying cranial modification practices differ as do the methods employed. Certain scholars presume it signified social stature similar to the modified bodies of elites in European history. Others speculate it was a form of a marker of ethnicity distinguishing one group from another. But maybe the most captivating theory stems from Inca cosmology, which held that shaping a child’s skull helped “anchor” the soul, ensuring it wouldn’t slip through soft spots on the skull. The practice held no semblance of cruelty and was viewed alternatively as a beautifying and protective ritual.
Modern Misinterpretations and Media Frenzy
The discovery of the skull sparked long standing controversies regarding extraterrestrial “alien” contact with ancient cultures, a concept championed by pseudoscience. Still, specialists confirm those changes were completely anthropogenic. “The notion that these skulls are the remnants of aliens is a recent fantasy,” explains biological anthropologist Dr. Heidi Dawson-Hobbis. “What we’re observing is rich cultural tradition, without hints of any ‘visitors’.”
What This Discovery Tells Us About Ancient Argentina
The skull looks very strange, like an alien’s, but the find is important for learning about Argentina’s pre-Inca cultures. The child’s head was turned 90 degrees, and they were buried in a fetal position with pottery and llama bones from the Inca era that had been burned. The skull’s age of 1100–1300 CE, on the other hand, suggests that the burial happened before the Incas took over, pointing to an earlier culture that shaped skulls.
Conclusion: A Window into Humanity’s Diverse Past

The Argentine “alien” skull serves as an example of how easily modern societies can misinterpret ancient customs. While some sensationalist theorists argue it is evidence of aliens, archaeologists perceive it as a form cultural practice which linked people across the globe and thousands of years. As scholars learn more about the child’s skeletal remains, they reveal not only the tale of an individual child but the collective narrative of humanity’s identity, of belief, and the tragedies societies undertook to carve out their intended existence one skull at a time.
