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 a vital role within this prehistoric lake ecosystem.\u003c\/p\u003e\n\u003cp data-start=\"816\" data-end=\"1295\"\u003eThis authentic fossil was discovered in a quarry approximately 20km outside Kemmerer, Wyoming — an area internationally celebrated for producing exceptionally preserved fossil fish. After the fish died, it drifted to the quiet lakebed where it was rapidly buried beneath ultra-fine sediment. Low oxygen conditions slowed decomposition and prevented scavengers from disturbing the remains, preserving delicate skeletal structures and anatomical details with extraordinary clarity.\u003c\/p\u003e\n\u003cp data-start=\"1297\" data-end=\"1737\"\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 in the world. Fossils from this region provide researchers with an exceptionally 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=\"1739\" data-end=\"1907\"\u003eThis authentic Knightia fossil is more than a collector’s specimen — it is a genuine relic from a prehistoric freshwater world preserved in stone for millions of years.\u003c\/p\u003e\n\u003ch2 data-section-id=\"19tr6of\" data-start=\"1914\" data-end=\"1965\"\u003e\u003cbr\u003e\u003c\/h2\u003e\n\u003ch2 data-section-id=\"19tr6of\" data-start=\"1914\" data-end=\"1965\"\u003eThe Details You Need — Forever Gems Fossil Facts\u003c\/h2\u003e\n\u003cp data-start=\"1967\" data-end=\"2544\" style=\"padding-left: 40px;\"\u003e✓ \u003cstrong data-start=\"1969\" data-end=\"1982\"\u003eSPECIMEN:\u003c\/strong\u003e Fossil Fish\u003cbr data-start=\"1994\" data-end=\"1997\"\u003e✓ \u003cstrong data-start=\"1999\" data-end=\"2011\"\u003eSPECIES:\u003c\/strong\u003e \u003cem data-start=\"2012\" data-end=\"2030\"\u003eKnightia eocaena\u003c\/em\u003e\u003cbr data-start=\"2030\" data-end=\"2033\"\u003e✓ \u003cstrong data-start=\"2035\" data-end=\"2043\"\u003eAGE:\u003c\/strong\u003e Eocene Epoch (Approx. 50 Million Years Old)\u003cbr data-start=\"2087\" data-end=\"2090\"\u003e✓ \u003cstrong data-start=\"2092\" data-end=\"2106\"\u003eFORMATION:\u003c\/strong\u003e Green River Formation\u003cbr data-start=\"2128\" data-end=\"2131\"\u003e✓ \u003cstrong data-start=\"2133\" data-end=\"2146\"\u003eLOCATION:\u003c\/strong\u003e Near Kemmerer, Wyoming, USA\u003cbr data-start=\"2174\" data-end=\"2177\"\u003e✓ \u003cstrong data-start=\"2179\" data-end=\"2197\"\u003eSPECIMEN SIZE:\u003c\/strong\u003e 116mm x 120mm x 9mm Approximately\u003cbr data-start=\"2230\" data-end=\"2233\"\u003e✓ \u003cstrong data-start=\"2235\" data-end=\"2249\"\u003eFISH SIZE:\u003c\/strong\u003e 98mm x 30mm Approximately\u003cbr data-start=\"2275\" data-end=\"2278\"\u003e✓ \u003cstrong data-start=\"2280\" data-end=\"2291\"\u003eWEIGHT:\u003c\/strong\u003e 261 grams\u003cbr data-start=\"2300\" data-end=\"2303\"\u003e✓ \u003cstrong data-start=\"2305\" data-end=\"2322\"\u003ePRESERVATION:\u003c\/strong\u003e Natural fossil fish preserved in fine-grained limestone\u003cbr data-start=\"2378\" data-end=\"2381\"\u003e✓ \u003cstrong data-start=\"2383\" data-end=\"2400\"\u003eAUTHENTICITY:\u003c\/strong\u003e Genuine prehistoric freshwater fossil specimen\u003cbr data-start=\"2447\" data-end=\"2450\"\u003e✓ \u003cstrong data-start=\"2452\" data-end=\"2464\"\u003eDISPLAY:\u003c\/strong\u003e Ideal for fossil collections, educational displays, and natural history décor\u003c\/p\u003e\n\u003cp data-start=\"2546\" data-end=\"2716\" data-is-last-node=\"\" data-is-only-node=\"\" style=\"text-align: center;\"\u003e\u003cstrong\u003eOwn a genuine relic from Earth’s ancient freshwater past and let this beautifully preserved Knightia fossil become a timeless connection to the lakes of the Eocene world.\u003c\/strong\u003e\u003c\/p\u003e","brand":"ForeverGems_Tuc","offers":[{"title":"Default Title","offer_id":45772735578308,"sku":"S322","price":670.0,"currency_code":"ZAR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0273\/1599\/4699\/files\/S322FishFossil_1.webp?v=1780405690","url":"https:\/\/www.forevergems.co.za\/products\/authentic-green-river-formation-fish-fossil-kemmerer-wyoming-quarry-limestone-slab","provider":"ForeverGems_SA","version":"1.0","type":"link"}
