Trilobites – the prehistoric creatures that roamed the earth over 250 million years ago and have now been extinct for more than 200 million years – have always fascinated paleontologists and collectors alike. Trilobite fossils from the Cambrian period can now be found in certain areas of Utah.

In this article, well take a closer look at these remarkable creatures, where to find them, and how to go about doing so safely and legally.

Trilobite Fossils in Utah

In the vast expanse of Utahs high desert regions, trilobite collectors have found a mecca for their hobby. The Wheeler Amphitheater area in the House Range of Millard County near Delta has prolific deposits of Cambrian trilobites.

5) Weeks Formation and Wellsville Mountains

Utah offers a wealth of trilobites to collectors, and two of the most significant regions for hunting them down are the Weeks Formation and the Wellsville Mountains. While both of these areas are known for providing pockets of trilobite-rich shale, collectors should be aware of certain guidelines about collecting on BLM lands and the restrictions on private collecting or commercial use.

Pockets of Trilobite-rich Shale

The Weeks Formation covers a vast region of the western United States, including parts of Utah, Colorado, and Wyoming. Within the formation, the Spence Shale is known to contain excellent trilobite specimens.

The Wellsville Mountains, on the other hand, provide a rich source of trilobites from the Lanston Formation. Collectors will find plentiful opportunities to dig for these ancient creatures on BLM lands.

Before embarking on a trilobite expedition, it is essential to have a clear understanding of the guidelines and restrictions for collecting on BLM lands. Collectors should thoroughly research the site they wish to explore, obtain the necessary permits, and ensure they follow all the rules to ensure both their own safety and to protect the environment for future generations.

Recommended for Experienced Collectors

While beginners may find the idea of backpacking, walking, and climbing in search of trilobite fossils appealing, it is recommended that collectors be experienced before embarking on a hunt in the Weeks Formation or Wellsville Mountains. These regions offer a challenging terrain, and some of the trilobites found can be challenging to remove from the rock and quite large.

The Spence Shale is known to produce very delicate trilobites, and collectors should be prepared to handle them with care to ensure that they remain intact. The Lanston Formation in the Wellsville Mountains, on the other hand, is known to produce some of the largest trilobite specimens found anywhere.

The BLM has specified that private collecting is limited to 25 pounds per day per individual, with the material to be used for personal, educational, or scientific purposes. Commercial use of the excavated material, on the other hand, is prohibited.

In conclusion, the trilobite enthusiast can find joy at the Weeks Formation and Wellsville Mountains. However, it is important to take necessary precautions, do thorough researching of the areas before visiting them, and follow the guidelines that have been put forth by the BLM.

These regions offer a wealth of opportunities to excavate ancient trilobites, but collectors should be well versed in the hunting process before going on an expedition. With experience, patience, and a little bit of luck, the intrepid trilobite collector can mine for these prehistoric gems and build an impressive collection.

In conclusion, Utah is home to a variety of trilobite sites, each with its own unique offerings and guidelines. Whether visiting a private field, a free public site, or exploring BLM lands, collectors can discover the wonder of these fascinating prehistoric creatures.

Always keep in mind the necessary safety precautions, necessary permits, and regulations governing the sites. With the right preparation, tools, experience, and a little bit of luck, collectors can uncover some remarkable specimens, adding to their collections while also advancing our collective understanding of the Earth’s ancient history.
