This large plate of 80 x 48 cm is covered with uncountable individuals of brittle stars of the genus Ophiura. A mass mortality scene from the Ordovician, freezing a scene of ancient sea life. Fossil Ophiura from Morocco are ancient brittle stars found in marine sedimentary rocks, such as limestone and shale. This fossil plate dates back to the Ordovician period, when Morocco was covered by ancient seas. Preserved with detailed features, they help scientists understand the evolution of echinoderms and ancient marine ecosystems. Fossil-rich regions like the Anti-Atlas yield these specimens, which are valuable to both paleontologists and fossil collectors. They highlight Morocco's rich paleontological heritage and its diverse ancient marine environments. The heavy plate will be shipped very securely on a palette via FedEx or can be collected in person in the Netherlands. In this case, shipping costs will be reimbursed.
