Rare Green River Gleichenia Fern Fronds

Description: This is an excellent find for the specialist collector of Green River fossil flora. There appear to be three distinct branches with individual fern leaves attached. The ferns are partial to complete. The largest one is 2 ¼” in length. The plate is covered with other leaf species and one needs a bit of diligence to discern the fern branching patterns.

The Green River Formation holds one of the world’s richest depositories of fossil leaves, plants, vines and aquatic vegetation. My provider alone shows over seventy species he collects. Surely there are many more found. Not only is the variety of plant life phenomenal, the preservation is often superb. The Green River fossils I am offering are collected with the permission of the property owner on privately held land.
