The Morrison Formation

The Morrison Formation preserves an amazing ecosystem that sustained an unusual and incredible environment of adversity with some of the largest land animals that ever walked the planet. Normal in Late Jurassic North America was huge, and while sauropods would reach larger sizes, their dominance and diversity would never again reach this height.
