Knightia was one of the most common fish species inhabiting these calm freshwater environments, swimming in large schools through warm waters and feeding on small aquatic organisms. Closely related to modern herring and sardines, Knightia played a vital role within this prehistoric lake ecosystem.\u003c\/p\u003e\n\u003cp data-start=\"826\" data-end=\"1289\"\u003eWhen this fish died, it drifted to the quiet lakebed where it was rapidly buried beneath ultra-fine sediment. Low oxygen conditions prevented scavenging and decay, preserving delicate details such as fins, scales, and skeletal structures with extraordinary clarity. Over millions of years, these sediments compressed and hardened into the fine-grained limestone that made the Green River Formation internationally renowned for its exceptional fossil preservation.\u003c\/p\u003e\n\u003cp data-start=\"1291\" data-end=\"1699\"\u003eToday, the Green River Formation is regarded as one of the world’s most scientifically important fossil localities, preserving an incredibly detailed record of prehistoric freshwater ecosystems. Fossils from this region help scientists better understand ancient climates, lake environments, and the evolution of early freshwater life while offering collectors a breathtaking window into Earth’s distant past.\u003c\/p\u003e\n\u003cp data-start=\"1701\" data-end=\"1882\"\u003eThis authentic fossil fish specimen is more than a collectible — it is a beautifully preserved snapshot of life from an ancient Eocene lake preserved in stone for millions of years.\u003c\/p\u003e\n\u003ch2 data-section-id=\"19tr6of\" data-start=\"1889\" data-end=\"1940\"\u003e\u003cbr\u003e\u003c\/h2\u003e\n\u003ch2 data-section-id=\"19tr6of\" data-start=\"1889\" data-end=\"1940\"\u003eThe Details You Need — Forever Gems Fossil Facts\u003c\/h2\u003e\n\u003cp data-start=\"1942\" data-end=\"2521\" style=\"padding-left: 40px;\"\u003e✓ \u003cstrong data-start=\"1944\" data-end=\"1957\"\u003eSPECIMEN:\u003c\/strong\u003e Fossil Fish\u003cbr data-start=\"1969\" data-end=\"1972\"\u003e✓ \u003cstrong data-start=\"1974\" data-end=\"1986\"\u003eSPECIES:\u003c\/strong\u003e \u003cem data-start=\"1987\" data-end=\"2005\"\u003eKnightia eocaena\u003c\/em\u003e\u003cbr data-start=\"2005\" data-end=\"2008\"\u003e✓ \u003cstrong data-start=\"2010\" data-end=\"2018\"\u003eAGE:\u003c\/strong\u003e Eocene Epoch (Approx. 50 Million Years Old)\u003cbr data-start=\"2062\" data-end=\"2065\"\u003e✓ \u003cstrong data-start=\"2067\" data-end=\"2081\"\u003eFORMATION:\u003c\/strong\u003e Green River Formation\u003cbr data-start=\"2103\" data-end=\"2106\"\u003e✓ \u003cstrong data-start=\"2108\" data-end=\"2121\"\u003eLOCATION:\u003c\/strong\u003e Near Kemmerer, Wyoming, USA\u003cbr data-start=\"2149\" data-end=\"2152\"\u003e✓ \u003cstrong data-start=\"2154\" data-end=\"2172\"\u003eSPECIMEN SIZE:\u003c\/strong\u003e 129mm x 81mm x 12mm Approximately\u003cbr data-start=\"2206\" data-end=\"2209\"\u003e✓ \u003cstrong data-start=\"2211\" data-end=\"2225\"\u003eFISH SIZE:\u003c\/strong\u003e 56mm x 27mm Approximately\u003cbr data-start=\"2251\" data-end=\"2254\"\u003e✓ \u003cstrong data-start=\"2256\" data-end=\"2267\"\u003eWEIGHT:\u003c\/strong\u003e 207 grams\u003cbr data-start=\"2277\" data-end=\"2280\"\u003e✓ \u003cstrong data-start=\"2282\" data-end=\"2299\"\u003ePRESERVATION:\u003c\/strong\u003e Natural fossil fish preserved in fine-grained limestone\u003cbr data-start=\"2355\" data-end=\"2358\"\u003e✓ \u003cstrong data-start=\"2360\" data-end=\"2377\"\u003eAUTHENTICITY:\u003c\/strong\u003e Genuine prehistoric freshwater fossil specimen\u003cbr data-start=\"2424\" data-end=\"2427\"\u003e✓ \u003cstrong data-start=\"2429\" data-end=\"2441\"\u003eDISPLAY:\u003c\/strong\u003e Ideal for fossil collections, educational displays, and natural history décor\u003c\/p\u003e\n\u003cp data-start=\"2523\" data-end=\"2700\" data-is-last-node=\"\" data-is-only-node=\"\" style=\"text-align: center;\"\u003e\u003cstrong\u003eOwn a perfectly preserved survivor from the ancient lakes of Wyoming and let this remarkable Knightia fossil bring the story of prehistoric freshwater life into your collection.\u003c\/strong\u003e\u003c\/p\u003e","brand":"ForeverGems_Tuc","offers":[{"title":"Default Title","offer_id":45772648710340,"sku":"S341","price":540.0,"currency_code":"ZAR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0273\/1599\/4699\/files\/S341FishFossil_1.webp?v=1780406649","url":"https:\/\/www.forevergems.co.za\/products\/authentic-green-river-formation-fish-fossil-kemmerer-wyoming-limestone-slab","provider":"ForeverGems_SA","version":"1.0","type":"link"}
