Knightia was one of the most common fish species inhabiting these calm freshwater waters, swimming in large schools and feeding on small aquatic organisms. Closely related to modern herring and sardines, Knightia played an important role within this thriving prehistoric lake ecosystem.\u003c\/p\u003e\n\u003cp data-start=\"832\" data-end=\"1287\"\u003eThis authentic fossil was discovered in a working quarry approximately 20km from Kemmerer, Wyoming — an area internationally recognised for producing some of the world’s finest fossil fish specimens. After the fish died, it drifted gently to the calm lakebed where it was rapidly buried beneath ultra-fine sediment. Low oxygen conditions prevented decay and disturbance, preserving delicate skeletal structures and body details with extraordinary clarity.\u003c\/p\u003e\n\u003cp data-start=\"1289\" data-end=\"1725\"\u003eOver millions of years, these sediments compressed and hardened into the fine-grained limestone that made the Green River Formation one of the most scientifically important fossil localities on Earth. Fossils from this formation provide researchers with an incredibly detailed record of prehistoric freshwater ecosystems, helping scientists better understand ancient climates, lake environments, and the evolution of early fish species.\u003c\/p\u003e\n\u003cp data-start=\"1727\" data-end=\"1893\"\u003eThis authentic Knightia fossil is more than a collector’s specimen — it is a genuine snapshot of prehistoric freshwater life preserved in stone for millions of years.\u003c\/p\u003e\n\u003ch2 data-section-id=\"19tr6of\" data-start=\"1900\" data-end=\"1951\"\u003e\u003cbr\u003e\u003c\/h2\u003e\n\u003ch2 data-section-id=\"19tr6of\" data-start=\"1900\" data-end=\"1951\"\u003eThe Details You Need — Forever Gems Fossil Facts\u003c\/h2\u003e\n\u003cp data-start=\"1953\" data-end=\"2532\" style=\"padding-left: 40px;\"\u003e✓ \u003cstrong data-start=\"1955\" data-end=\"1968\"\u003eSPECIMEN:\u003c\/strong\u003e Fossil Fish\u003cbr data-start=\"1980\" data-end=\"1983\"\u003e✓ \u003cstrong data-start=\"1985\" data-end=\"1997\"\u003eSPECIES:\u003c\/strong\u003e \u003cem data-start=\"1998\" data-end=\"2016\"\u003eKnightia eocaena\u003c\/em\u003e\u003cbr data-start=\"2016\" data-end=\"2019\"\u003e✓ \u003cstrong data-start=\"2021\" data-end=\"2029\"\u003eAGE:\u003c\/strong\u003e Eocene Epoch (Approx. 50 Million Years Old)\u003cbr data-start=\"2073\" data-end=\"2076\"\u003e✓ \u003cstrong data-start=\"2078\" data-end=\"2092\"\u003eFORMATION:\u003c\/strong\u003e Green River Formation\u003cbr data-start=\"2114\" data-end=\"2117\"\u003e✓ \u003cstrong data-start=\"2119\" data-end=\"2132\"\u003eLOCATION:\u003c\/strong\u003e Near Kemmerer, Wyoming, USA\u003cbr data-start=\"2160\" data-end=\"2163\"\u003e✓ \u003cstrong data-start=\"2165\" data-end=\"2183\"\u003eSPECIMEN SIZE:\u003c\/strong\u003e 130mm x 91mm x 7mm Approximately\u003cbr data-start=\"2217\" data-end=\"2220\"\u003e✓ \u003cstrong data-start=\"2222\" data-end=\"2236\"\u003eFISH SIZE:\u003c\/strong\u003e 57mm x 18mm Approximately\u003cbr data-start=\"2263\" data-end=\"2266\"\u003e✓ \u003cstrong data-start=\"2268\" data-end=\"2279\"\u003eWEIGHT:\u003c\/strong\u003e 155 grams\u003cbr data-start=\"2288\" data-end=\"2291\"\u003e✓ \u003cstrong data-start=\"2293\" data-end=\"2310\"\u003ePRESERVATION:\u003c\/strong\u003e Natural fossil fish preserved in fine-grained limestone\u003cbr data-start=\"2366\" data-end=\"2369\"\u003e✓ \u003cstrong data-start=\"2371\" data-end=\"2388\"\u003eAUTHENTICITY:\u003c\/strong\u003e Genuine prehistoric freshwater fossil specimen\u003cbr data-start=\"2435\" data-end=\"2438\"\u003e✓ \u003cstrong data-start=\"2440\" data-end=\"2452\"\u003eDISPLAY:\u003c\/strong\u003e Ideal for fossil collections, educational displays, and natural history décor\u003c\/p\u003e\n\u003cp data-start=\"2534\" data-end=\"2700\" data-is-last-node=\"\" data-is-only-node=\"\" style=\"text-align: center;\"\u003e\u003cstrong\u003eBring the ancient lakes of the Eocene into your collection and secure this beautifully preserved Knightia fossil before it disappears into another collection forever.\u003c\/strong\u003e\u003c\/p\u003e","brand":"ForeverGems_Tuc","offers":[{"title":"Default Title","offer_id":45772692717764,"sku":"S321","price":210.0,"currency_code":"ZAR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0273\/1599\/4699\/files\/S321FishFossil_1.webp?v=1780405636","url":"https:\/\/www.forevergems.co.za\/products\/green-river-formation-fish-fossil-authentic-kemmerer-wyoming-limestone-specimen","provider":"ForeverGems_SA","version":"1.0","type":"link"}
