Name:
Fern Fronds and Sphenophyllum
Age: Pennsylvanian
Formation: Llewellyn Formation
Location: Near St. Clair, Pennsylvania

This is a large plate of fossil seed ferns from the classic St. Clair, Pennsylvania locality. The seed ferns are preserved as a thin film of white pyrophyllite on black shale. The plate has many fronds intact, but the large Sphenophyllum is the key feature of the piece! The fossils have very nice contrast and excellent detail. And the back side of the plate also has plant material preserved. This is a very displayable association of unusual plants from the Pennsylvanian Period.
