OWEN Department of Palaeontology, The Natural History Museum, Cromwell Road, London SW7 5BD INTRODUCTION Brachiopods were particularly rare in the Maastrichtian sedi- ments of the United Arab Emirates-Oman borders region. Despite intensive collecting only four specimens were found, all coming from the lower Loftusia-hch beds of the Qahlah Formation exposed at Jebel Huwayyah (see introduction for locality details). These four specimens belong to a hitherto undescribed genus of terebratulid.
