This is a detailed fossil leaf of Beringiaphyllum cupanoides, from the Fort Union Formation, Glendive Montana. It is from the Paleocene, or approximately 60 million years old. The dark orange preservation contrasts well against the shale, and all the veins of the leaves can be seen in good relief. There may be some touchups to the surface of the leaves where some of it flaked onto the negative during collection. It comes with an acrylic display stand.
