Fossil Seed Ferns
Age: Pennsylvanian
Formation: Llewellyn Formation
Location: St. Clair, Pennsylvania
Size: Plate is 15.0" X 22.7"
This is a HUGE plate of fossil seed ferns from the classic St. Clair, Pennsylvania locality. It is very hard to get a slab this large from this location. And even more difficult to get a slab of this size that is as nice as this one. The seed ferns are preserved as a thin film of white pyrophyllite on black shale. There are several different types of seed ferns represented on the plate. The plate has many fronds intact, and several are over 5 inches long! The fossil plants have excellent color and contrast and exhibit superb detail. There are also many seed ferns on the reverse side of the plate. This is a museum quality plate of Coal Age plants from Pennsylvania.
