Toadstool’s Trackway
Imagine miniature rhinos, pig-like animals, giant tortoises, and tiny horses traveling the plains before you. These are just a few of the animals that came here to hunt, rest, and drink from the wide shallow river, leaving their prints in the sandbars and shores.

The Golden Age of Mammals
The Eocene and Oligocene geologic epochs - The Golden Age of Mammals - are magnificiently preserved here. The White River Group represents the "type section," or geologic standard, for rocks during this time. Scientists from all over the world come here to study the fossils and trackways contained within the ancient rock, as well as the geologic history that shaped the land and supported life.

African Savanna Here?
Toadstool Geologic Park captures a slice of life when Nebraska resembled the savannahs of Africa and supported an abundance of wildlife. In time, these animals became extinct, or evolved into modern species, including zebras, camels, horses, and rhinoceroses, after migrating to Africa.
