North America, United States, Wyoming, Green River Formation, Eocene Epoch, ca. 53.5 to 48.5 million years ago. This limestone fossil panel preserves three prehistoric Dolomites fish in exceptional detail, with delicate ribs, fin rays, and distinct spines sharply exposed against the pale matrix - a striking study in ancient anatomy and natural preservation. Sourced from one of the world's most celebrated fossil beds, this specimen offers a direct glimpse into the freshwater ecosystems of prehistoric Wyoming. The Eocene was the warmest epoch of the Cenozoic Era, with average temperatures near 86F (30C) - nearly 30 degrees warmer than today - a hothouse world of no ice caps, vast inland seas, and lush, water-covered landscapes stretching across continents that would already have looked remarkably familiar to modern eyes. Size: 18.75" L x 13.6" W (47.6 cm x 34.5 cm)

Provenance: private Colorado, USA collection
