Photo Essay: Unearthing the Lost World Below a Petrified Forest

In Arizona’s Petrified Forest National Park, researchers are scouring the fossil-rich surface and drilling deep into ancient rocks to learn more about what happened during the late Triassic, some 201 million to 235 million years ago. It was a time when the world underwent repeated climate shifts and catastrophic mass extinctions, and both early dinosaurs and mammals evolved. What the researchers learn here may not only allow them to write a precise chronology of the period, but shed light on wider questions including how climate swings work, and how they affect ecosystems.

I think it’s fantastic that scientists can take a core sample and find out what the levels of carbon dioxide were 200 million years ago. That’s hard to believe.

Would love your thoughts, please comment.x
