Fossil Leaf Plate - Green River Formation, Utah

This is an interesting fossil leaf plate from the Green River Formation, Utah. It contains a 4.9" horsetail (Equisetum) stem, two Mimosites leaflets, the largest .6", five willow leaves, the largest complete one 1.9", a 4.8" primary vein of an unidentifed leaf and a 14.7" willow twig curling through the center. This is a very busy specimen that would make an interesting display.

While the Green River Formation is best know for its fish fossils, other areas produce incredible plant fossils.

Comes with an acrylic stand.
