Abstract
Rudist buildups were described from many horizons within the Cretaceous strata of the Arabian Basin.<br>The most prominent among these were described from the Shuiaba Formation (Aptian) in the major<br>oilfields of the Arabian Gulf region. They were documented also from the Mauddud Formation (Aptian)<br>in the eastern offshore areas of Saudi Arabia and southeast Iraq and from the Mishrif Formation<br>(Albian-Cenomanian) in the southern Arabian Gulf and southern Iraq (e.g. Majnoon field). More varied<br>buildups were found in the Upper Cretaceous carbonates of the Simsima Formation (Maastrichtian) in<br>Oman and the UAE, the Hartha Formation (Campanian) in central and west Iraq and from Wadi Sir<br>Formation (Turonian) in Jordan.
