They had tubular feet enabling them to move. Brittle stars on the other hand had narrower, more flexible arms that they wiggled in order to move around the sea floor. The type of brittle star fossils found in Morocco are of the genus Ophiura and are characterized by a disc-like body with long, thin legs radially arranged around it. In fossil plates their wavy arms give the appearance of dancing.\u003c\/span\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cspan\u003e\u003cstrong\u003eTrilobites\u003c\/strong\u003e are extinct hard shelled marine arthropods with amazingly great diversity. It is estimated there were over 15,000 known species of Trilobita, making them the most diverse animal life form that ever existed on earth. In Morocco, new Trilobite specimens are being discovered every year. Trilobites are are important as paleo-zoic guide fossils, having existed for over 270 million years. They began their existence during the early Cambrian time period (520 mya), long before dinosaurs existed but went extinct around 250 mya, before dinosaurs died out.\u003c\/span\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cspan\u003e\u003cstrong\u003eCrinoids\u003c\/strong\u003e began life some 530 million years ago. They are plant-like sea creatures, some of which either root themselves underwater or gently float along the sea bed, gathering tiny organisms for nourishment. Crinoids often resemble flowers planted in the sea floor, giving them their name from the Greek word for \"Lilly.\" Crinoids are remarkably adaptable animals and they are a good example of what is referred to as a \"living fossil\", as many different species live today but only deep in our seas and oceans.\u003c\/span\u003e\u003c\/p\u003e","brand":"Daves Rock Shop","offers":[{"title":"Default Title","offer_id":45983824707663,"sku":"i-fsl-2502-ds","price":2000.0,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0638\/5568\/9807\/files\/IMG_7201d.jpg?v=1782764159","url":"https:\/\/davesrockshop.com\/products\/starfish-crinoid-trilobite-mortality-plate-w-stand","provider":"Daves Rock Shop","version":"1.0","type":"link"}
