Fossil Leaf Association Beringiaphyllum & Zizyphoides - Montana

This is a beautifully preserved group of fossil leaves from two different species—Beringiaphyllum cupanoides, and Zizyphoides flabellum. They are leaf fossils from the Fort Union Formation of Montana. The largest Beringiaphyllum leaf is 4.9" long, and the larger of the two Zizyphoides flabellum is 2.2". They are 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 a display stand.
