Description: Frozen in time, this genuine insect fossil was unearthed from the sedimentary layers of Garfield County, Colorado—a region celebrated for its exceptional fossil beds. Dating back approximately 50 million years to the Eocene Epoch, these delicate impressions capture an extraordinary glimpse into prehistoric life shortly after the age of dinosaurs. The fine-grained shales of this area preserved even the most fragile creatures with astonishing detail, making each fossil a tiny, irreplaceable window into ancient ecosystems.

Garfield County is part of the renowned Green River Formation, an area famous for its breathtaking fossil preservation. During the Eocene, this region was a lush landscape of subtropical forests, rivers, and lakes teeming with life. Insects were not only abundant but vital to the environment, pollinating plants and forming critical links in the food web. The fine preservation of these specimens often reveals intricate wing venation, segmented legs, and body textures rarely seen in fossils, offering collectors and scientists alike an unmatched study of early Cenozoic biodiversity.
