Very Large Museum Display Slab of Fossil Ferns

Name: Fossil Seed Fern Slab

Age:  Pennsylvanian

Formation:  Llewellyn Formation

Location:  Near St. Clair, Pennsylvania

Size: Plate is 23.7 inches tall!

Price: SOLD

Specimen SSA714

This is a huge 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, let alone a slab of this size that is this nice! The entire slab is covered with large seed fern fronds and branches. There are several different types of seed ferns preserved, and there are even some excellent Sphenophyllum "flowers" displayed on the plate (see close-up photo). The distinct ferns are preserved as a thin film of white pyrophyllite on black shale - quite striking! The fossil plants have beautiful color and contrast and exhibit superb detail. And this whole slab (almost a full TWO feet tall!) is one piece - it has never been broken or pieced together! This is a huge, top quality display plate of Pennsylvanian plants from a classic location - simply amazing!
