Trilobite fossils are extremely popular with collectors. They are from an extinct group of arthropods that lived from the early Cambrian Period until near the end of the Permian Period. These hard-shelled prehistoric animals lived on the sea floors and reefs for millions of years. They developed into complex and beautiful animals, resulting in a variety of fossil-types.
The Antelope Springs area in Millard County is one of the best places on earth to find trilobite fossils. There are both public and private quarries, so make sure you know where you are. The private quarries are well marked. These private areas charge a fee to dig in their quarries, but can almost guarantee that you will find trilobites.
