3.9" Red Fossil Leaf (Fraxinus) - Montana

This is a 3.9" long fossil leaf of Fraxinus sp. from the Fort Union Formation of Montana. Fraxinus (English name ash) is a genus of flowering plants in the olive and lilac family. It contains 45–65 species of usually medium to large trees, mostly deciduous though a few subtropical species are evergreen.

The color of the rock and the leaf is rather unusual, and different than most of the leaves seen from the Fort Union Formation. It was collected from a locality where a fire in a nearby coal seam "cooked" the rock at some point in the past. This changed the color and gave it a chalky texture.

The leaf has some small areas of touchup work done to it where some of the color had flaked onto the negative when split. It comes with an acrylic display stand.
