Huge 3.7" Fossil Leaf (Beringiaphyllum) - Montana

This is a big, and very detailed Beringiaphyllum cupanoides leaf fossil from the Fort Union Formation of Montana. The leaf is 3.7" long. It is from the Paleocene epoch, or approximately 60 million years old. The dark brown preservation of the leaf fossil contrasts well against the lighter shale, and all the veins of the leaf can be seen in good relief. It comes with an acrylic display stand.
