During the Eocene, this region was covered by a series of calm lakes where layer upon layer of ultra-fine sediment accumulated on the lake floor. These sediments rapidly buried plants, fish, insects, and other organisms, protecting them from decay before gradually hardening into limestone over millions of years.\u003c\/p\u003e\n\u003cp data-start=\"1601\" data-end=\"2081\"\u003eToday, the Green River Formation provides one of the most complete records of an ancient freshwater ecosystem anywhere in the world. Its remarkable preservation has made it internationally famous among scientists and fossil collectors alike.
