A large number of 300-million-year-old lepidodendron fossils have recently been discovered in the suburbs of Yangquan City, north China's Shanxi Province. Experts say so far, they are the best-preserved ones unearthed in China. Lepidodendron is an extinct genus of primitive lycopodian vascular plants. It was a major coal-forming plant that existed around 300 million years ago.
