Prof. YANG Ruidong at the Guizhou University announced recently that he and his team have found a lichen like plant dated back to 520 million years ago. Named as Parafunaria sinensis Yang, the plant is the earliest lichen like plants discovered so far in the world. The finding advances the fossilized record of lichen plants by 70 million years. The specimen collected show leave-shape ring growing process, capsule and sophisticated roots that are uniquely possessed by lichen plants. These plants are believed heading for a transition to the lichen plants.
