The Impact of Secondary Mortuary Practices on Representation and Distribution of Commingled Elements from Umm an-Nar Human Skeletons in Communal Tombs

Abstract Commingled human skeletons have the potential to reveal information about ancient funerary traditions through detailed bioarchaeological analyses of element representation (via minimum number of individuals, or MNI) and postmortem distribution. While MNI estimates are often presented in a perfunctory way, calculations using more nuanced methods may offer insight into taphonomic alteration and mortuary practices no longer visible to archaeologists. At the Early Bronze Age communal tombs of Unar 1 and 2 at the Shimal Necropolis in Ras al-Khaimah, United Arab Emirates (UAE), MNI counts using skull, leg, and foot fragments varied dramatically, probably a result of differences in cortical bone density but also of cremation practices. Additionally, the presence of more elements from the left side of the skeleton suggests continuity with Neolithic interments in which individuals were preferentially laid on their right sides. Complex arrays of internal tomb chambers likewise demonstrate no particular preference for certain skeletal elements, indicating bone was not intentionally relocated to different areas of the tomb following cremation. These patterns differ from other tombs in the region, highlighting the need to more critically assess mortuary practices through “back-to-basics” approaches involving MNI estimates, particularly when involving large numbers of individuals represented by commingled and fragmentary bone.
