Late Cretaceous Echinoids from the Seymareh member (Lopha Limestone member), KabirKuh Anticline, Southwest of Iran

In the present study, The Seymareh or Lopha Limestone Member (Gurpi Formation) in Kabir Kuh Section, have been Selected. The member has yielded a rich echinoid fauna and 21 species of Echinoid belonging to 14 genera are recognized and described. The Kabir Kuh section yielded two regular echinoid taxa: Salenia nutrix and Goniopygus superbus, one holectypoid taxa: Coptodiscus noemiae, two conulid taxa: Conulus douvillei and Globator bleicheri, six cassiduloid taxa: Parapygus longior, Parapygus declivis, Parapygus inflatus, Parapygus vassilini, Vologesia tataosi and Pygurostoma morgani, one holasteroid species: Hemipneustes persicus and nine spatangoid taxa: Iraniaster douvillei, I. morgani, I. nodulosus, Hemiaster noemiae, Hemiaster opimus, Mecaster kanepanensis, Mecaster longus, Proraster morgani and Epiaster lamberti. The taxon association indicates a Campanian age. Some of the taxa are known from the similar Campanian age in Saudi Arabia such as: Coptodiscus noemiae. Some specimens are reported also from Campanian deposits of Afghanistan such as: Hemiaster noemiae, H. opimus and Parapygus vassilini. Globator bleicheri and Salenia nutrix are recorded from Maastrichtian deposits of UAE and Oman.
