Did You Know?
During the Age of Dinosaurs, a warm, shallow sea covered the Great Plains, including what is now Badlands. Since dinosaurs were land creatures, no fossils of these animals have been found in the park. Giant marine lizards called mosasaurs swam in the ancient sea, along with sea turtles and fish.
