Abstract

Mishan Formation in the Gohreh section (north of Bandar Abbas) is investigated in order to identify echinoid species. Systematic study of echinoids shows presence of two orders in the studied area; Spatangoida and Clypeasteroida. Five described species are: Clypeaster sp., Clypeaster goirensis, Schizaster granti, Moira adamthi, Maretia ranjitpurensis.The co-occurrence of index associated foraminifers such asOrbulina universaand Globigerinoides trilobus shows the Middle Miocene age for the echinoid bearing beds.
