Western Utah is one of the best-known Cambrian fossil localities in the world. The Wheeler Shale and Marjum Formation, strata of Middle Cambrian age, exhibit various exposures throughout the House Range and nearby mountain ranges west of the town of Delta, Utah. The Wheeler Shale is named for a major feature in the House Range, the Wheeler Amphitheater. The Wheeler Shale contains interbeds of shaley limestone, mudstone, and thin platy limestone. Much of the Wheeler Shale is not particularly fossiliferous, but certain layers contain abundant trilobites and other shelly fossils.
