This incredible mold and cast of Elrathia kingi  comes from You Dig Fossils in Delta, Utah. If you bought a trilobite in a gift store or rock shop, chances are it came from this quarry. The day we went to the quarry it was empty, so the guy who was working that day showed us exactly where to go and what to look for in the rock.
