White Mound is located in the Arbuckle Mountains about 4 miles west of Nebo, Oklahoma. The area is privately held, so be sure to get permission before entering. There is a fee for collecting at this site. The fossil bearing strata is the Devonian aged Haragan Formation.
Marine fossils are plentiful, although most are brachiopods.
Each found about a half-dozen trilobites, some in better shape than others with most being fragments. A trained eye will yield some nice specimens and be a wonderful learning experience for children. Even children at young ages can find ancient marine creatures at White Mound - including trilobites, bryozoa, brachiopods, gastropods, and more.
