Previous studies of this dramatic event mainly have focused on evolutionary patterns in animal groups prior to the extinction, and on their recovery during the Early Triassic [2].Although some macroevolutionary scenarios have been postulated for the changes in land-plant vegetation through the Permian and Triassic,the severity of extinction and,the timing and radiation pattern in the recovery of plant groups during the Early Triassic are still debated [3].Hitherto there has been little information about plant life in the wake of the end-Permian extinction event,mainly because of the scarcity of records of earliest Triassic plant-bearing deposits worldwide.Here we report on an Early Triassic flora from Southwest China that provides a rare glimpse into the post-extinction vegetation in the (sub)tropics of Cathavsia.展开更多
