One of the unsolved mysteries at the Fossil Butte National Monument are the great die-offs that are recorded on a slab called the Green River Formation. The die-offs are called mass mortality layers and have the fossilized remains of thousands of fish that are said to have died suddenly. Scientists and researchers are unsure what may have killed the fish and constant research to solve the mystery has been underway. Although millions of the fossil remains that have been discovered in Fossil Butte National Monument are fish, there are other marine and land life that have been unearthed as well. The formation of early primates, crocodiles, turtles, plants, and lizards have also been discovered. Visitors to the park who discover fossils outside of the trail are required to leave them undisturbed.
