In a recent construction project, Mexican archaeologists unearthed a collection of ancient bones.

According to a press release from the National Institute of Anthropology and History (INAH) issued on Feb. 26, the discovered burial site is traced back to the pre-Columbian era.

The excavation took place in the town of Pozo de Ibarra, coinciding with a sewage-related construction initiative.

The INAH press release highlighted that the uncovered skeletons were part of a “complex funerary system.”

Notably, at least seven well-preserved skulls exhibited signs of “cranial modification,” a practice that, as per INAH, might have been carried out for aesthetic reasons.

The intentional arrangement of the bones further underscores the significance of this archaeological find, Fox News reported.

“It is a funerary system composed of a primary burial, that is, the skeleton maintains the anatomical relationship, accompanied by a concentration of human bone remains deposited without anatomical relationship, which have a particular arrangement,” the press release, which was translated from Spanish to English, explained.
