Two Fossil Leaves - Beringiaphyllum And Zizyphoides - Montana

These are detailed Beringiaphyllum cupanoides and Zizyphoides flabellum leaf fossils from the Fort Union Formation of Montana. They are from the Paleocene epoch, or approximately 60 million years old. The dark brown preservation of the leaf fossils contrasts well against the lighter shale, and all the veins of the leaves can be seen in good relief. There is some minor restoration to the surface to touchup bits that flaked onto the negative.

This specimen comes with an acrylic display stand.
