Name:
Rhus nigricans (Sumac Leaf)
Age: Eocene
Formation: Green River Formation
Location: Bonanza, Utah
Size: Leaf is 2.2 inches long
This is an excellent fossil leaf. It is a beautiful Rhus nigricans (Sumac Leaf) from the Green River Formation of Utah. This leaf is amazingly complete - all of the features of the leaf are present and wonderfully displayed. The serrated margins of the leaf are easily seen, and the venation is clearly defined. A distinct petiole is still tightly attached to the base of the leaf. The natural, dark-brown color of the leaf contrasts strikingly with the lighter-colored matrix. And, best of all, this is a split pair fossil - both part and counterpart of the leaf are present, and both halves are included here! This is a very uncommon split pair Sumac leaf from Utah.
