Arthropod Dominance Revealed in Ancient Fossil Site.
A new fossil site in Taichoute, Morocco, has revealed that giant arthropods dominated the seas 470 million years ago, some potentially up to 2 meters long. The site, part of the wider Fezouata Biota, offers new insights into paleontological and ecological research. The Fezouata Shale has been recognized as one of the 100 most important geological sites worldwide for understanding evolution during the Early Ordovician period.
