Socio‐cultural innovations of the Final Umm an‐Nar period (c.2100–2000 BCE) in the Oman peninsula: new insights from Ra's al‐Jinz RJ‐2

Abstract The Early Bronze Age site of RJ ‐2, located close to the coastal village of Ra's al‐Jinz on the eastern Omani coast (Niyabat Ra's al‐Hadd), was the focus of archaeological investigations for over two decades. The latest campaigns of excavation unearthed an architectural complex (Building XII ) dated to the very end of the Umm an‐Nar period (Final UaN, c .2100–2000 BCE ), previously attested on site by poorly preserved remains. This paper presents the remains explored during the most recent fieldwork, focusing on the stratigraphic‐structural sequence and the spatial layout. It also considers the transformations affecting structural evidence and material culture during this period, at both local and regional level, highlighting their significance for a comprehensive assessment of the last occupations related to the Early Bronze Age in south‐eastern Arabia. The paper concludes by showing how the Final Umm an‐Nar phase represents an age of substantial socio‐cultural innovations, which most likely shaped the transition towards the following Wadi Suq period.
