LATE CAMPANIAN-MAASTRICHTIAN CORALS Order COENOTHECALIA Bourne, 1900 128 Family HELIOPORIDAE Moseley, 1876 128 Genus POLYTREMA CYSd'Orbigny, 1849 128 Polytremacis blainvillei (Michelin, 1841) 128 P. edwardsana (Stoliczka, 1873) 128 Acknowledgements 128 References 128 93 SYNOPSIS. 43 species of 34 genera of scleractinian corals and 1 genus of octocoral from the Qahlah and Simsima Formations of the United Arab Emirates-Oman border region are described. The faunas are dominated by colonial forms including the taxa Actinastrea, Columactinastraea, Stylophora, Monticulastraea, Neocoenia, Stephanaxophyllia, Columastrea, Paraplacocoenia, Astrogyra, Placosmilia, Diplocoenia, Calamophylliopsis, Agathelia, Diploctenium, Cladophyllia, Glenarea, Dendrophyllia, Barysmilia, Orbignygyra, Astraraea, Pseudofavia, Goniopora, Actinacis, Brachycoenia, Mesomorpha, Fungiastrea, Brachyphyllia, Aspidastraea. The occurrence of solitary corals is strongly dominated by Cunnolites, with a minor appearance of Montlivaltia, Aulosmilia, Phragmosmilia, Diegosmilia and Trochocyathus. INTRODUCTION During the period 1991-1995 members of the Palaeontology De- partment of The Natural History Museum collected and described Upper Cretaceous macrofossils during their investigations of the Qahlah and Simsima Formations in the Oman Mountains of the United Arab Emirates-Oman border area. Previous results have been published on the lithofacies of the Qahlah and Simsima Formations (Smith etai, 1995a), echinoids (Smith, 1995), ammo- nites (Kennedy, 1995), nautiloids and inoceramids (Morris, 1995), bryozoans (Taylor, 1995), brachiopods (Owen, 1995), and rudists (Morris & Skelton, 1995). In addition, studies on the palaeoenvironment dealing with echinoid-mollusc-coral assem- blages provided the first information about the coral associations (Smiths al, 1995b). This paper adds to our knowledge of these Upper Cretaceous faunas by providing a detailed description
