A rectangular sedimentary matrix displaying at least four fossil Knightia sp. fish. [No Reserve]
ProvenanceEx Lincolnshire, UK, collection.
FootnotesIn southwest Wyoming (and parts of Colorado and Utah) in the Green River Formation are found some of the world's most outstanding specimens of fossil fish. The Green River system was composed of three lakes: Lake Ulinta, Lake Gosiute and Fossil Lake. These Eocene lakes lay in a series of intermountain basins formed by geological events that uplifted the Rocky Mountains during the early Tertiary time. The climate was much different from the desert-like climate of this area today. Both the fauna (crocodiles, alligators, boa constrictors and some subtropical fish families) and the flora (such as large palm trees) indicate a climate much like that found along the Gulf Coast today. Large amounts of ash found in the sediments indicate that volcanoes were particularly active at this time.

The primitive-looking coelacanth was thought to have gone extinct with the dinosaurs 65 million years ago. Its discovery in 1938, by a South African museum curator on a local fishing trawler, fascinated the world and ignited a debate about how this bizarre lobe-finned fish fits into the evolution of land animals. It is often referred to as a ‘living fossil’, referencing its anomalous form in the fossil record.
