Typically dating back to the Cretaceous period, roughly 120 million years ago, it testifies to the biological richness of the tropical seas of the Cenomanian, a period marked by the greatest depth ever reached by the sea. The Cymatoceras is recognized by its massive and strongly ribbed shell. It is a nautiloid shape, approaching its current descendant: the nautiles. These are much rare than most Ammonites. \u003c\/span\u003e\u003c\/p\u003e\n\u003cp class=\"MsoNormal\" style=\"line-height: normal;\"\u003e\u003cb\u003eASSOCIATED MINERALS \u003cbr\u003e\u003c\/b\u003eAragonite, Calcite, Pyrite, Quartz\u003cbr\u003e\u003c\/p\u003e\n\u003cp class=\"MsoNormal\" style=\"line-height: normal;\"\u003e\u003cb\u003eASSOCIATED FEATURES \u003cbr\u003e\u003c\/b\u003eIridescent\u003cbr\u003e\u003c\/p\u003e\n\u003cp class=\"MsoNormal\" style=\"line-height: normal;\"\u003e\u003cb\u003eASSOCIATED COLOURS \u003cbr\u003e\u003c\/b\u003eBrown, Red, White, Green \u003cbr\u003e\u003c\/p\u003e\n\u003cp class=\"MsoNormal\" style=\"line-height: normal;\"\u003e\u003cb\u003eMOHS HARDNESS SCALE\u003ci\u003e\u003cbr\u003e\u003c\/i\u003e\u003c\/b\u003e3.5 to 5 \u003cbr\u003e\u003c\/p\u003e\n\u003cp class=\"MsoNormal\"\u003e\u003cb\u003ePRODUCT DATA \u003cbr\u003e\u003c\/b\u003eLocality = Maintirano, Madagascar\u003cbr\u003eGrade = Very Good Grade\u003cspan style=\"mso-spacerun: yes;\"\u003e                      \u003c\/span\u003e\u003cbr\u003eSize = 96 - 157  mm\u003c\/p\u003e","brand":"FOSSIL - Ammonite","offers":[{"title":"Default Title","offer_id":50275977035969,"sku":"184-255-260530BM","price":3175.2,"currency_code":"ZAR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/2066\/6451\/files\/184255_5.jpg?v=1780324254","url":"https:\/\/www.toprocks.com\/products\/polished-cymatoceras-nautilus-ammonite-fossils-x-2-from-maintirano-madagascar","provider":"Toprock Gemstones and Minerals ","version":"1.0","type":"link"}
