Argentine Northwest
In February 2021, archaeologists from the University of Buenos Aires–National Scientific and Technical Research Council announced the discovery of 12 graves dated to 6,000-1,300 years ago in Argentine Northwest. Researchers also revealed necklaces and pendants next to some of the bodies. According to archaeologist Leticia Cortés, there were many kinds of burial methods, in individual or collective graves, and also in the posture of the bodies. Some were hyperflexed, like squatting, with the shoulders touching the knees.
