Name:
Fossil Seed Fern Plate
Age: Pennsylvanian
Formation: Llewellyn Formation
Location: Near St. Clair, Pennsylvania
Size: Plate is 15 inches across!
This is a very large plate of fossil seed ferns from the Coal Age deposits near St. Clair, Pennsylvania. It is very hard to get a slab this large from this site, and even more difficult to get a slab of this size that is as nice as this one. The entire slab is covered with large seed fern fronds and branches - one of the fronds is over TEN inches long - the largest single frond from this site we have ever seen! 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, and even the horsetail Sphenophyllum is represented. 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 Pennsylvanian plants from a classic location.
