SKU Number: SQ1033187
Olenoides rooksi Middle Cambrian, Marjum Formation, Millard County, Utah.
This is an extremely rare and spiny trilobite that is very rarely available on the market. The spines are large and free standing with the occipital spine curving back towards the axial lobe.
This is a very high-end trilobite for the very discerning collector. Very likely the only one currently being offered on the open market!!!
This example comes from the Marjum Formation that overlies the Wheeler Shale.

Additional Information
Western Utah is the home of one of the best-known Cambrian fossil localities in the world. The slopes of Swasey Peak in the House Range, seen above, are composed of a rock layer known as the Wheeler Shale, with the overlying Marjum Formation forming the top of the peak. The Wheeler Shale and Marjum Formation, strata of Middle Cambrian age, are exposed throughout the House Range and nearby mountain ranges west of the town of Delta, Utah. The Wheeler Shale is named for a great bowl-shaped feature in the House Range known as the Wheeler Amphitheater, while the Marjum Formation is named for its outcrops at Marjum Pass, also in the House Range. Much of the Wheeler Shale is quite unfossiliferous, but certain layers contain abundant trilobites and other shelly fossils. The Wheeler Shale and Marjum Formation also contain a diverse biota of soft-bodied fossils, including many of the same taxa found in the more famous Burgess Shale.
Olenoides is a member of the order: Corynexochida,
