3.35" Fossil Hackberry Leaf - Montana

This is a detailed, Celtis aspera leaf fossil from the Fort Union Formation of Montana. 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. There is some minor touchups to the surface to touchup bits that flaked onto the negative.

It comes with an acrylic display stand.
