Fossil Leaves (Zizyphoides & Dogwood) - Montana

This is a nice pair of two different leaf fossils from the Fort Union Formation of Montana. They are from the Paleocene, or approximately 60 million years old. The dark orange preservation 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.

The larger leaf is a beautifully preserved Zizyphoides flabellum and the smaller one is Cornus swingii part of a genus commonly known as dogwoods.
