Here is an unidentified seed from a time when Colorado had a very different climate. The Early Eocene was the warmest interval since the days of the dinosaurs. Tropical forest covered much of the continents. Even Antarctica was ice-free at the time. Climates would start to trend cooler a few million years later.
