It is also Wyoming's State Fossil. Its length reaches up to 25 cm (10 in). About fifty million years ago, ancient Fossil Lake existed in present-day southwest Wyoming. Of its estimated maximum size of 930 square miles, roughly 500 square miles of sediment are still present. The central 230 square miles of the ancient lakebed contain exceptionally fossil-rich sediments and related geological features, including deltas, beaches, springs, and rocks from both the central and nearshore environments. The unique chemistry of Fossil Lake prevented decay and scavenging of dead organisms, while thin layers of alternating limestone accumulated slowly. This process created laminated limestones that hold the highest concentration of fossil fish in the world. These fossils, along with other aquatic organisms and geological features, make Fossil Lake the best Paleogene record of freshwater lake ecosystems globally. Since its discovery in the 1870s, many well-preserved fossil fish have been found. The laminated limestone also preserves an entire aquatic ecosystem: cyanobacteria, plants, insects, crustaceans (such as shrimp, crawfish, and ostracods), amphibians (including frogs and primitive salamanders), alligators, turtles, birds, and mammals, including the oldest pantolestid (an otter-like animal). The surrounding subtropical terrestrial ecosystem is also represented by rare fossils, including a horse, two snakes, lizards, two bat species, birds, apatemyid (an arboreal insectivore), miacad (a primitive carnivore), insects, and more than 325 types of leaves, seeds, and flowers. \u003c\/span\u003e\u003c\/p\u003e\n\u003chr\u003e\n\u003cp\u003e\u003cimg height=\"402\" width=\"804\" src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/1250\/0441\/files\/KnightiaEocaenafossilfish_480x480.jpg?v=1709136067\" alt=\"\"\u003e\u003c\/p\u003e\n\u003chr id=\"horizontalrule\"\u003e\n\u003cp\u003e\u003cstrong\u003e\u003cbr\u003e\u003cbr\u003e\u003c\/strong\u003e\u003c\/p\u003e","brand":"Tynskys 25","offers":[{"title":"Default Title","offer_id":52293144543512,"sku":"06JVV245","price":39.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/1250\/0441\/files\/5U8A3945_0b9fbc2c-3e47-45ff-af09-091428e3e57d.jpg?v=1781643996","url":"https:\/\/www.fossilageminerals.com\/products\/xl-4-6-knightia-eocaena-fossil-fish-green-river-fm-wy-eocene-age-coa-and-stand-06jvv245","provider":"Fossil Age Minerals","version":"1.0","type":"link"}
