Large Fossil Seed Fern Plate from Pennsylvania
Stock Number  WFERN703

Name:   Fossil Seed Fern Fronds
Age:  Pennsylvanian
Formation:  Llewellyn Formation
Location:  Near St. Clair, Pennsylvania
Size:  Plate is 15.5 inches diagonal!

This is a very large plate of plant fossils from the now-closed location at St. Clair, Pennsylvania. The fossils are preserved as a thin film of white pyrophyllite on black shale. The detail of the fossils is quite nice, and the plants are nicely showcased on the large plate of shale. There are at lease two different types of ferns preserved on the plate. And the back side of the slab also has two nice fern fronds fossilized. This is a very fine example of a large plate of fossil fern fronds from the Coal Regions of Pennsylvania.
