Overview of U-Dig Trilobite Quarry

So, what is U-Dig Trilobite Quarry? Allow us to explain. This local attraction boasts 40 acres of the best trilobite shale in the world. A trilobite is an extinct form of marine life (about 550 million years old!) that once roamed the sea floor. However, all that remains now is an enormous fossil collection ranging in specimens sized one-eighth of an inch to two inches long.

U-Dig Quarry provides every customer with a high-end experience searching for their very own trilobite fossils. They provide all the necessary tools for excavation and allow guests to keep the ancient goodies they find.
