Fossil Bird Feather
Dating to the Eocene epoch, these two meticulously preserved bird feathers derive from the Green River Formation in Uintah County, Utah—a site of unparalleled paleontological significance. Fifty million years ago, Fossil Lake's specialized geochemical environment created ideal conditions for exceptional fossil preservation, preventing organic decay and enabling the formation of finely laminated limestone layers. This ancient freshwater ecosystem, spanning hundreds of square miles, captured an entire biological community: aquatic organisms, terrestrial fauna, and diverse flora in remarkable detail. The laminated deposits have yielded some of the world's finest fossils since their discovery in the 1870s, documenting a complete subtropical ecosystem from cyanobacteria to early mammals. These delicate feather specimens exemplify the extraordinary preservation quality characteristic of Green River Formation fossils, offering collectors authentic windows into Paleogene life systems.
