The precious rocks were thought to hold special spiritual or supernatural significance for the Preclassical Mayan people. The obsidian stones were discovered in Ceibal, Guatemala, with details reported in a study in the Journal of Field Archaeology.
In one burial at the site, obsidian stones were found in a grave for two sacrificed children, between two and four years of age. The children were buried face to face, with a long obsidian blade and an unshaped piece of obsidian alongside them.
