WVGES Museum Receives Loan of Trilobite Specimens

Trilobites From Monongalia County

Michael Dunn of Mineral, Virginia, discovered these trilobites in an abandoned limestone quarry near Greer in Monongalia County. His collection consists of several pygidia (or tails) and one complete, well preserved, enrolled specimen. Only one trilobite genera Kaskia is known from the upper Mississippian strata of the Appalachians, (Brezinski, 1988, 1999). These specimens are assigned to the species Kaskia chesterensis. This collection represents a new locality for this species. Other fauna at this locality include brachiopods, blastoids, and crinoid stems. Shown in the photographs are a few of the trilobite pygidia and both sides of the enrolled specimen. The enrolled specimen has also been digitally unrolled to show a complete specimen. These trilobite specimens are 0.5 to 1.5 inches long. Our thanks go out to Mr. Dunn for the loan of this trilobites for study and display here.
