Indication of a High Social Status (image) University of Bonn Caption Scientists from the University of Bonn discovered a mass grave in the Classic Maya city Uxul (Mexico). Some of the skulls featured tooth incrustations with jade -- a popular body adornment in the Classic Maya society which due to the material's scarcity was reserved to persons of high social status. For these incrustations, stone tools were employed to drill small cavities in the tooth. These cavities were thereupon filled with fitting pieces of jade.
