A trove of seaweed-like fossils unearthed in southern China may be some of the oldest plants ever discovered. Until now the earliest definitive evidence of complex creatures resembling modern organisms was about 580 million years old. This new series of fossils predates those by anywhere from 20 million to 56 million years. "It's not the oldest multicellular life," remarks a co-author of the study. "But it is a collection of the oldest diverse, complex and macroscopic multicellular life."
