A pair of researchers has found evidence at the Tulán-52 excavation in Chile that suggests the need for a reinterpretation of how the stone complex was used. In their paper published in the journal Antiquity, Lautaro Núñez with Universidad Católica del Norte and Catherine Perlès with Allée de l’Université, suggest the new evidence shows more social complexity among the later hunter-gatherers who built and used the complex than previously thought.
