Toadstool Geologic Park is a collection of badlands formations found in the Oglala National Grassland of Nebraska. The rock formations found in this park formed 38-24 million years ago and are related to the same rocks in South Dakota’s Badlands National Park. These parks also share many fossil animals, like ancient dogs, horses, and rhinoceroses. Many of these fossil animals went extinct and do not have modern analogues. Perhaps one of the most exciting preservations in Toadstool Geologic Park is the .75 mile-long trackway that reveals an ancient pursuit of hungry entelodonts chasing two species of rhinoceros down a stream channel.
