The Green River Formation fossil palm is a well-preserved fossil from an ancient species of palm tree that lived around 50 million years ago during the Eocene epoch. These fossils are found in the Green River Formation, a sedimentary deposit located in parts of Wyoming, Utah, and Colorado. The palm fossils from this region are remarkable for their detail, often showing intricate leaf patterns and even textures. This area was once a subtropical environment with lush vegetation, and the palm fossils are a testament to the region's warm climate during that time. These fossils are highly prized by collectors and provide valuable insights into the ancient ecosystems of North America.
