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 an important role within this thriving prehistoric ecosystem.\u003c\/p\u003e\n\u003cp data-start=\"841\" data-end=\"1319\"\u003eThis authentic fossil was discovered in a quarry approximately 20km outside Kemmerer, Wyoming — an area internationally recognised for producing some of the finest fossil fish specimens in the world. After the fish died, it drifted gently to the quiet lakebed where it was rapidly buried beneath ultra-fine sediment. Low oxygen conditions prevented scavenging and slowed decomposition, preserving delicate skeletal structures and fine anatomical details with remarkable clarity.\u003c\/p\u003e\n\u003cp data-start=\"1321\" data-end=\"1768\"\u003eOver millions of years, these sediments compressed and hardened into the fine-grained limestone that made the Green River Formation world famous for its exceptional fossil preservation. Today, fossils from this formation provide scientists with one of the most detailed records of ancient freshwater ecosystems ever discovered, helping researchers better understand prehistoric climates, lake environments, and the evolution of early fish species.\u003c\/p\u003e\n\u003cp data-start=\"1770\" data-end=\"1947\"\u003eThis authentic Knightia fossil is more than a collector’s specimen — it is a beautifully preserved snapshot of prehistoric freshwater life frozen in stone for millions of years.\u003c\/p\u003e\n\u003ch2 data-section-id=\"19tr6of\" data-start=\"1954\" data-end=\"2005\"\u003e\u003cbr\u003e\u003c\/h2\u003e\n\u003ch2 data-section-id=\"19tr6of\" data-start=\"1954\" data-end=\"2005\"\u003eThe Details You Need — Forever Gems Fossil Facts\u003c\/h2\u003e\n\u003cp data-start=\"2007\" data-end=\"2585\" style=\"padding-left: 40px;\"\u003e✓ \u003cstrong data-start=\"2009\" data-end=\"2022\"\u003eSPECIMEN:\u003c\/strong\u003e Fossil Fish\u003cbr data-start=\"2034\" data-end=\"2037\"\u003e✓ \u003cstrong data-start=\"2039\" data-end=\"2051\"\u003eSPECIES:\u003c\/strong\u003e \u003cem data-start=\"2052\" data-end=\"2070\"\u003eKnightia eocaena\u003c\/em\u003e\u003cbr data-start=\"2070\" data-end=\"2073\"\u003e✓ \u003cstrong data-start=\"2075\" data-end=\"2083\"\u003eAGE:\u003c\/strong\u003e Eocene Epoch (Approx. 50 Million Years Old)\u003cbr data-start=\"2127\" data-end=\"2130\"\u003e✓ \u003cstrong data-start=\"2132\" data-end=\"2146\"\u003eFORMATION:\u003c\/strong\u003e Green River Formation\u003cbr data-start=\"2168\" data-end=\"2171\"\u003e✓ \u003cstrong data-start=\"2173\" data-end=\"2186\"\u003eLOCATION:\u003c\/strong\u003e Near Kemmerer, Wyoming, USA\u003cbr data-start=\"2214\" data-end=\"2217\"\u003e✓ \u003cstrong data-start=\"2219\" data-end=\"2237\"\u003eSPECIMEN SIZE:\u003c\/strong\u003e 137mm x 71mm x 5mm Approximately\u003cbr data-start=\"2270\" data-end=\"2273\"\u003e✓ \u003cstrong data-start=\"2275\" data-end=\"2289\"\u003eFISH SIZE:\u003c\/strong\u003e 99mm x 34mm Approximately\u003cbr data-start=\"2315\" data-end=\"2318\"\u003e✓ \u003cstrong data-start=\"2320\" data-end=\"2331\"\u003eWEIGHT:\u003c\/strong\u003e 106 grams\u003cbr data-start=\"2341\" data-end=\"2344\"\u003e✓ \u003cstrong data-start=\"2346\" data-end=\"2363\"\u003ePRESERVATION:\u003c\/strong\u003e Natural fossil fish preserved in fine-grained limestone\u003cbr data-start=\"2419\" data-end=\"2422\"\u003e✓ \u003cstrong data-start=\"2424\" data-end=\"2441\"\u003eAUTHENTICITY:\u003c\/strong\u003e Genuine prehistoric freshwater fossil specimen\u003cbr data-start=\"2488\" data-end=\"2491\"\u003e✓ \u003cstrong data-start=\"2493\" data-end=\"2505\"\u003eDISPLAY:\u003c\/strong\u003e Ideal for fossil collections, educational displays, and natural history décor\u003c\/p\u003e\n\u003cp data-start=\"2587\" data-end=\"2751\" data-is-last-node=\"\" data-is-only-node=\"\" style=\"text-align: center;\"\u003e\u003cstrong\u003eOwn a genuine piece of Earth’s ancient freshwater history and let this extraordinary Knightia fossil bring the prehistoric lakes of the Eocene into your collection.\u003c\/strong\u003e\u003c\/p\u003e","brand":"ForeverGems_Tuc","offers":[{"title":"Default Title","offer_id":45772745212100,"sku":"S323","price":670.0,"currency_code":"ZAR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0273\/1599\/4699\/files\/S323FishFossil_1.webp?v=1780405733","url":"https:\/\/www.forevergems.co.za\/products\/authentic-green-river-formation-fish-fossil-kemmerer-wyoming-quarry-limestone-specimen","provider":"ForeverGems_SA","version":"1.0","type":"link"}
