Fossil site reveals giant arthropods dominated the seas 470 million years ago uniofexeter SciReports
Early evidence from the site at Taichoute, once undersea but now a desert, records numerous large"free-swimming" arthropods.
Dr. Xiaoya Ma, from the University of Exeter and Yunnan University, added:"While the giant arthropods we discovered have not yet been fully identified, some may belong to previously described species of the Fezouata Biota, and some will certainly be"Nevertheless, their large size and free-swimming lifestyle suggest they played a unique role in these ecosystems.
Fossils discovered in these rocks include mineralised elements , but some also show exceptional preservation of soft parts such asAnimals of the Fezouata Shale, in Morocco's Zagora region, lived in a shallow sea that experienced repeated storm and wave activities, which buried the animal communities and preserved them in place as exceptional fossils.
Dr. Lukáš Laibl, from the Czech Academy of Sciences, who had the opportunity to participate in the initial fieldwork, said, "Taichoute is not only important due to the dominance of large nektonic arthropods.
