Populus wilmattae
Age: Eocene

Size: Leaf is 5.4" long including petiole
This is an extremely attractive fossil leaf. It is a
leaf of Populus wilmattae, a poplar, from the Green River Formation of Utah. This heart-shaped leaf has a somewhat rounded base and a very long acuminate apex which is unusually intact to the tiny, tiny tip. The venation of the leaf is quite distinct and easily seen with the naked eye. The complete petiole is still tightly attached to the base of the leaf. The fossil has excellent, natural color and contrast and is almost perfectly centered on the rectangular plate of matrix. This is a very displayable specimen of a poplar leaf from the Eocene.
