Recently, an international research team led by Professor WANG Yongdong from the Nanjing Institute of Geology and Palaeontology, Chinese Academy of Sciences (NIGPAS) conducted a multidisciplinary integrated study on the Middle Jurassic floras of Central Iran. The research clarified the floral composition, palaeoecological and palaeoenvironmental conditions, and Eurasian palaeobiogeographic affinities of the region, challenging the long-standing classical hypothesis of widespread homogeneous Middle Jurassic vegetation across Eurasia by Vakhrameev. The findings have been published in the international geoscience journal Palaeogeography, Palaeoclimatology, Palaeoecology.
