Cerrejón also happens to be one of the world’s richest, most important fossil deposits, providing scientists with a unique snapshot of the geological moment when the dinosaurs had just disappeared and a new environment was emerging. “Cerrejón is the best, and probably the only, window on a complete ancient tropical ecosystem anywhere in the world,” said Carlos Jaramillo, a paleontologist at the Smithsonian Tropical Research Institute. “The plants, the animals, everything. We have it all, and you can’t find it anywhere else in the tropics.”

Fifty-eight million years ago, a few million years after the fall of the dinosaurs, Cerrejón was an immense, swampy jungle where everything was hotter, wetter and bigger than it is today. The trees had wider leaves, indicating greater precipitation—more than 150 inches of rain per year, compared with 80 inches for the Amazon now. Mean temperatures may have hovered in the mid- to high-80s Fahrenheit or higher. Deep water from north-flowing rivers swirled around stands of palm trees, hardwoods, occasional hummocks of earth and decaying vegetation. Mud from the flood plain periodically coated, covered and compressed the dead leaves, branches and animal carcasses in steaming layers of decomposing muck dozens of feet thick.
