Ancient Life: Trilobite Fossils

Get ready for a trip back in time! The Marble Mountains are famous for their amazing fossils. These fossils are found in layers of sedimentary rock. This rock formed from sand and mud over millions of years.

The Marble Mountains Fossil Beds are a special place. Here, scientists have found fossils that are about 550 million years old! These ancient fossils belong to creatures called trilobites. Trilobites were sea animals that lived long before dinosaurs. They were some of the first animals on Earth to have eyes and hard skeletons. Finding these fossils helps us learn about life from a very, very long time ago.

Trilobite Wilderness Area

The Marble Mountains are protected as part of the Trilobite Wilderness. This special area was created in 1994 by the U.S. Congress. A wilderness area is a place where nature is kept wild and untouched. It helps protect the land, plants, and animals.
