Name:
Fossil Fern Plate
Age: Pennsylvanian
Formation: Llewellyn Formation
Location: Near St. Clair, Pennsylvania
Size: Plate is 6.1 inches across
This is a nice, displayable fossil seed fern plate from the famous location near St. Clair, Pennsylvania. There are many nice fronds on the plate. The seed ferns are preserved as a thin film of white pyrophyllite on black shale. But the unusual feature of this fossil is there are different layers preserved - the top fern is on a layer that is partially covering the ferns on the lower layers! There are also some ferns preserved on the back side of the plate. This is a very cool grouping of Coal-Age ferns from the Keystone State.
