Only One Available: This is a nice example of a fossil Pecopteris fern found around the Pittsburgh area.
Pecopteris is a very common form genus of leaves. Most Pecopteris leaves and fronds are associated with the marattialean tree fern Psaronius. However, Pecopteris-type foliage also is borne on several filicalean ferns, and at least one seed ferfn. Pecopteris first appeared in the Devonian period, but flourished in the Carboniferous, especially the Pennsylvanian. Plants bearing these leaves became extinct in the Permian period.
This is by far one of the best fossil ferns you will find. This would display very well. It measures 3.5" x 3". Weighs 8.4 grams.
