Abstract

The Carboniferous region of Shahrud Gheshlagh is situated in Ramian Division of Gonbad - Kavous district, between Mazandaran and Semnan Provinces. This region is located 110 Km northeast of Shahrud and 15 Km west of Shahrud - Azad Shahr road.In this region, the sediments of Upper Trias-Lias possess a good extension and thickness; although the diversity and the distribution of plant fossils is fairly abundant, and no precise study has been yet achieved with regarding to their plant fossils.In this paper, 14 genera belonging to the following four phylum are recognized: Cycadophytes (6 genera), Ginkgophytes (2 genera), Phyllicophytes (4 gerera) and Coniferophytes (2 genera).Study of plant fossils of Carboniferous sediments of Shahrud Gheshlagh region, revealed that, the age of these sediments probably relate to the Upper Trias (Retian). This conclusion is based on the presence of Scytophyllum persicum which is characteristic of Upper Trias sediments, as well as, the absence of characteristic fossils of Lias. The flora of this period show more affinity with the plant fossils of North Hemisphere. Moreover, climatic conditions of the time of Carboniferous layer into MIBK under the same experimental conditions as samples.
