Large Museum Display Slab of Fossil Seed Ferns

Name: Fossil Seed Fern Slab

Age: Pennsylvanian

Formation: Llewellyn Formation

Location: Near St. Clair, Pennsylvania

Size: Plate is an amazing 22 inches across

Price: SOLD

Specimen SSS924

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! This plate was on loan and on display for four years at the Rocky Mountain Dinosaur Research Center Museum for four years, and we just got it back. The entire slab is covered with large seed fern fronds and branches. There are several different types of seed ferns represented on the plate. The seed ferns are preserved as a thin film of white pyrophyllite on black shale - quite striking! The fossil plants have excellent color and contrast and exhibit superb detail. And this whole slab (almost 2 feet across!) is one piece - it has never been broken or pieced together! This is an incredible, huge, top quality display plate of Pennsylvanian plants from a classic location.

This fossil was collected and obtained legally, and is also being sold legally. A Certificate of Authenticity from EXTINCTIONS is included with this specimen.
