Sourced from the Volga River region in Ulyanovsk, Russia, this piece captures the intersection of paleontology and mineralogy—where ancient marine reptile remains have been chemically altered by iron sulfide mineralization over millions of years.\n\nThe specimen measures 10 x 1.5 x 4.5 cm, offering substantial presence for display or study. Pyrite replacement specimens are prized by collectors for their rarity, visual contrast, and the geological narrative they tell about diagenetic processes in fossil-bearing formations. An excellent addition to paleontology or mineral collections seeking museum-quality character and scientific interest.","brand":"Sterling Mineral Imports","offers":[{"title":"Default Title","offer_id":48048705568989,"sku":"6","price":235.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0548\/9954\/0189\/files\/IMG-5468.heic?v=1781718131","url":"https:\/\/sterlingmineralimports.com\/products\/pliosaur-bone-pyrite-replacement-1","provider":"Sterling Mineral Imports","version":"1.0","type":"link"}
