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 MANY seed fern fronds and branches. There are several different types of seed ferns represented on the plate. The striking fossil ferns are preserved as a thin film of white pyrophyllite on black shale - fully natural! The fossil plants have excellent color and contrast and exhibit superb detail. And this whole slab (almost 2 1/2 feet across!) is one piece - it has never been broken or pieced together! This is a huge, beautiful, top quality display plate of Pennsylvanian plants from a classic location.
A Certificate of Authenticity from EXTINCTIONS is included with this specimen.
