The archaeological excavations along the route of packages 3 and 4 of the Batinah Expressway, Sultanate of Oman, conducted during the spring and summer of 2014, recorded over 60 archaeological sites over the 200km stretch of roadway cutting through the Batinah plain, north-west of Muscat. The majority of these sites were prehistoric tombs of varying ages. These excavations have allowed a re-thinking of the dating of some of these tombs, looking particularly at the structural styles of the tombs as well as their location in the landscape. It has also demonstrated techniques of rapid yet reliable excavation and recording techniques adapted from UK commercial archaeology for the Omani conditions. The report builds on the work of academic studies and adds a large dataset to the archaeology of the Batinah, Oman and the wider region. It is hoped that this will allow a wider scale reconsideration of the burial styles of the prehistoric Gulf.
