A team of researchers from Northwest University and Guizhou University, both in China and one from the U.S., has found and partially excavated a new treasure trove of marine fossils from the “Cambrian explosion” in southern China. In their paper published in the journal Science, the group describes what has been found thus far. Allison Daley, with the University of Lausanne, has published a Perspective piece on the work by the team in China in the same journal issue.
