Name:
Populus cinnamomoides
Age: Eocene
Formation: Green River Formation
Location: Bonanza, Utah
Size: Populus leaf is 1.35 inches long
This is a rare split pair specimen of Populus cinnamomoides from the Eocene 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 long 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 that also contains a distinct fossil Ant. 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 Populus cinnamomoides leaf and Ant from Utah.
