Como Bluff is a long ridge extending east–west, located between the towns of Rock River and Medicine Bow, Wyoming.

Nineteenth-century paleontologists discovered many well-preserved specimens of dinosaurs, as well as mammals, turtles, crocodilians, and fish from the Morrison Formation.

The discovery of dinosaurs at Como Bluff has been recounted numerous times, most notably by Schuchert and LeVene,[1] Shur,[2] Ostrom and McIntosh,[3] and Jaffe.

[5] The American Museum of Natural History (AMNH) excavated in 1897 [1]-1898 [2], finding two partial skeletons of sauropods.

Within a year, the historic Quarry 9 at Como was discovered, producing an astounding 250 specimens, which increased the knowledge of Jurassic mammals exponentially.
