Discovery of the first ancestors of scorpions, spiders and horseshoe crabs
Who were the earliest ancestors of scorpions, spiders and horseshoe crabs? A Ph.D. student from the University of Lausanne (Switzerland), with the support of a CNRS researcher, has identified a fossil that fills the gap between modern species and those from the Cambrian period (505 million years ago), solving a long paleontological mystery.
