Abstract

Palaeobotany is knowledge of composition of plant communities (occurrence) in geological time scale )Phanerozoic Eon). To reconsider the distribution of existing plants, we had to pay attention to past dominancy of the flora communities. The purpose of this research is study of a small part of Mesozoic flora in Iran. Based on the presence of several coal mines, abundant well-preserved PLANT MACROFOSSILs and samples of scattered wood fossils, KALAT AREA in Gheshlagh region, (midway Azadshahr to Shahroud) seams number 24 (K24) has been studied by this research. Collected plant remains systematically can be assigned to 3 genera of Mesozoic GYMNOSPERMS. These 3 genera have been described by this research. Based on the prevailing presence of Bennetittlaes, the presence of Podozamites as a conifer genus, Rhaeto-Liassic time can be dated for the KALAT AREA or Shemshak group (Shemshak Formation). In the basis of palaeobotanical evidences and comparing recovered flora to the present plants, the weather conditions during depositional time can reconstructed to a warm and semi-moisturized condition, therefore middle elevation forests were dense and mixed of evergreen and deciduous trees were dominated in that time.
