When the Amazon Flowed Backwards
What did life look like when the Amazon watershed flowed backwards? How did its direction shape the evolution of life around it? And what force could have possibly been strong enough to up-end one of the world’s mightiest rivers between then and now? ***** PBS Member Stations rely on viewers like you.

Eocene Climate and Environment
NOAA, Earth's Past Tropical Climate🌴🍍 The episode known as the Paleocene-Eocene Thermal Maximum (PETM) occurred 55-56 million years ago. During the PETM, the GLOBAL TEMPERATURE HAD RISEN BY AS MUCH AS 5-8°C (9-14°F) to an average temperature as high as 73°F. AROUND THIS TIME MUCH OF THE CONTINENTAL UNITED STATES HAD A SUB-TROPICAL ENVIRONMENT. This fossil palm is from Fossil Butte National Monument, Wyoming. Image courtesy U.S. National Park Service.

40 million years ago during the Eocene Epoch, west-central Yukon had a Mediterranean climate. Our Dr. Christopher West led research for a new study examining fossils from northwest of Dawson City, Yukon. Using plant fossils collected from the Fifteenmile River locality, researchers reconstructed the ancient Eocene environment. The result? Although this area was above the Arctic Circle during the Eocene, it had a Mediterranean climate and contained broadleaf forests that endured polar light seaso

Eocene Fossils and Paleontology
We’re excited to begin the full preparation process of this incredible fossil stingray, discovered within the Fossil Butte Member of the Green River Formation—an Eocene treasure dating back roughly 52 million years. This remarkable specimen was found by one of our guests, showcasing the unique hands-on opportunities that paleotourism provides. The preparation process begins with a precision piston-driven tool, carefully exposing the fossil from its limestone matrix while preserving delicate anat

Pt 5🐟 Carefully working down and across the posterior basal cartilages of this Heliobatis radians—discovered within the sandwich beds of the Fossil Butte Member—requires exceptional precision and control. This stage of fossil preparation focuses on exposing delicate anatomical structures while maintaining the integrity of the surrounding limestone matrix. Using fine pneumatic tools and gentle hand techniques, preparators gradually remove sediment millimeter by millimeter, revealing the intricat
