Ancient, Predatory "Lobster" is an Ancestor to All Modern Arthropods

As reported this week in the journal Paleontology, fossils of Yawunik were recently unearthed from Marble Canyon, part of the renowned Burgess Shale rock formation of British Columbia. This massive fossil bed holds specimens of many sea creatures that lived during the Cambrian period, the geologic era that saw a rapid diversification of marine life forms.
