Fossil plants from the Carboniferous to the late Permian period distributed over a vast area from the Kuznetsk Basin in Russia through Siberia to Primorsky Krai. About 600 species are known, including Gangamopteris. In the Carboniferous period, the world's flora split into the Lepidodendropsis flora and the Angara flora, and from the end of the Carboniferous to the Permian period, it is said that the world's flora split into four groups: Gondwana, Angara, Euramenia, and Cathaysia.
