Complex multicellular life discovered from before Cambrian explosion

Stromatolites dated to the Middle Cambrian Era

With the help of a team from the Chinese Academy of Sciences, Virginia Tech geobiologist Shuhai Xiao discovered fossils of some of the earliest known complex multicellular eukaryotes. The multicellular organisms found in the fossils from that time period, 600 million years ago, are more complex than expected (1). The […]
