These Madagascan specimens are preserved in Calcite within a Limestone matrix, and are renowned for their distinctive logarithmic spiral form and intricate suture patterns formed where internal chamber walls met the outer shell. Shell material is typically replaced by Calcite during fossilisation, producing warm creams, browns, and occasionally pyritised golden tones depending on the deposit. Madagascar's western sedimentary basins are among the most prolific Ammonite localities in the world, consistently producing well-preserved specimens across a range of sizes.\u003c\/p\u003e\n\u003cp class=\"MsoNormal\" style=\"line-height: normal;\"\u003e\u003cb\u003eASSOCIATED MINERALS \u003cbr\u003e\u003c\/b\u003eCalcite, Limestone\u003cbr\u003e\u003c\/p\u003e\n\u003cp class=\"MsoNormal\" style=\"line-height: normal;\"\u003e\u003cb\u003eASSOCIATED FEATURES \u003cbr\u003e\u003c\/b\u003ePolished Exterior, Intricate Suture Patterns, Fossil, Decorative, Sedimentary Matrix, Fluorescent\u003cbr\u003e\u003c\/p\u003e\n\u003cp class=\"MsoNormal\" style=\"line-height: normal;\"\u003e\u003cb\u003eASSOCIATED COLOURS \u003cbr\u003e\u003c\/b\u003eCream, Brown, Tan, Gold\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 to 3.5\u003cbr\u003e\u003c\/p\u003e\n\u003cp class=\"MsoNormal\"\u003e\u003cb\u003ePRODUCT DATA \u003cbr\u003e\u003c\/b\u003eLocality = Madagascar\u003cbr\u003eGrade = Very Good Grade\u003cspan style=\"mso-spacerun: yes;\"\u003e                      \u003c\/span\u003e\u003cbr\u003eSize = 332 x 263 x 88 mm\u003c\/p\u003e","brand":"FOSSIL - Ammonite","offers":[{"title":"Default Title","offer_id":50281914761409,"sku":"184-384-260601BM","price":7868.0,"currency_code":"ZAR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/2066\/6451\/files\/184384_8.jpg?v=1780492704","url":"https:\/\/www.toprocks.com\/products\/polished-xl-rare-phylloceras-genus-ammonite-fossil-x-1-from-tulear-madagascar","provider":"Toprock Gemstones and Minerals ","version":"1.0","type":"link"}
