During the Eocene, a chain of peaceful lakes occupied this region, where microscopic layers of sediment settled continuously across the lake floor. Organisms that came to rest in these calm waters were rapidly buried before decomposition could occur. Over millions of years, these sediments hardened into fine-grained limestone, preserving extraordinary details of prehistoric life.\u003c\/p\u003e\n\u003cp data-end=\"2079\" data-start=\"1625\"\u003eThe Green River Formation is renowned for producing some of the world's best-preserved fossils, providing scientists with an exceptional record of an ancient freshwater ecosystem.
