ABSTRACT
Silurian trilobites of the Niur Formation in the Robat-e-Gharebil area are described and illustrated. Three genera and five species are identified, including: Calymene dastanpouri sp. nov. Calymene sp., Flexicalymene meeki, Gravicalymene hagani and Dalmanites ypacarayensis. The palaeogeographic relationships of the Eastern Alborz Range with the Northern Gondwana supercontinent during the Late Palaeozoic are also considered. The Early Silurian trilobites of lower part of the Niur Formation were comparable with those of other parts of Iran, Southern Europe, Northern Africa, Middle East and South of China. This similarity suggests that the Robat-e-Gharebil area (Kopeh Dagh region) was part of the peri- Gondwana supercontinent during the Early Silurian.
