Rare Green River Cedrelospermum Plant Fossils with Seeds

The Green River Formation deposits of Wyoming, Colorado, and Utah are best known for their immaculately-preserved fish, but other examples are known as well, as this specimen attests. This is an example of a rarely –seen plant known as Cedrelospermum nervosum complete with leaves and seeds. This is the only example I have been able to offer, and is in a fine state of preservation.
