Visiting the Quarry

The Frenchman Mountain Trilobite Quarry is open to the public and located on public lands administered by the Bureau of Land Management (BLM). Access to the quarry is free and collecting “invertebrate fossils” is also free.

At the quarry, visitors can see trilobite fossils in their natural state, still embedded in the rock. Most of the fossiliferous material is fragmentary. It is important to bring a rock hammer and eye protection, and be sure to use caution and respect the fossils and the surrounding environment. If other fossils are found in the area, it is important to let the BLM know what was discovered.

Trilobite Hunting Tips

If you’re planning to visit the Frenchman Mountain Trilobite Quarry and hunt for fossils, here are a few tips to keep in mind:

• Wear sturdy shoes and bring plenty of water. The quarry is located in a desert environment, and the terrain can be rocky and uneven.
• Use a chisel and hammer to carefully chip away at the rock and reveal the fossils. Be sure to use caution and respect the fossils and the surrounding environment.
• Look for trilobite pygidia, or tails. These are often the most well-preserved parts of the trilobite and are easier to spot.
• Keep an eye out for other fossils, such as brachiopods and corals. These can be found in the same rock formations as trilobites.

A Brief History of Trilobites

Trilobites were marine creatures that first appeared in the Cambrian period and dominated the oceans all the way through the Permian period, between 541 and 252 million years ago. They are among the first known arthropods, a group of animals that includes insects, spiders, and crustaceans. Trilobites had segmented bodies, jointed legs, and a hard exoskeleton, which made them well-suited for life in the ocean. They came in a variety of shapes and sizes, ranging from less than an inch to over two feet in length.

Trilobites became extinct at the end of the Permian period, around 252 million years ago. However, their fossils can still be found in rock formations around the world. The trilobite fossils at the Frenchman Mountain Trilobite Quarry are particularly well-preserved and easily accessible, making it a valuable location for local fossil enthusiasts.
