چکیده
The colonial coral faunas of Tarbur Formation in the Zagros area (SW Iran) were studied in terms of paleontological criteria and faunal relationships with adjacent areas. 9 genera and 8 species of Scleractinian corals have been identified through the specimens collected from the rudistid carbonate units of Semirom section. Common stratigraphic ranges of determinate coral taxa with the presence of coexistence index fossils, give the age of Late Cretaceous (Maastrichtian) for these layers. The identified types of corals are containing endemic species with regional distribution and pandemic species which have a worldwide expansion. Comparing the present endemic taxa with those are reported from the other parts of eastern Tethyan realm (Arabian platform) such as Turkey, Saudi Arabia, UAE and Oman pointed out on clear faunal interaction between these areas during the Late Cretaceous.
