Zelkova (Keaki Tree Leaf) - Green River Formation

This is an Eocene aged fossil leaf from Zelkova nervosa also known as a Keaki Tree. The leaf is 1.78" tall (including the stem) and on a piece of shale matrix. It is beautifully preserved with crisp edges. Fine details are easily seen.

Slight variations of the leaves have been designated under the names Planata nervosa and Myrica praedrymeja, but they now all fall under the species name Zelkova nervosa.

It comes the Green River Formation and the area in Uintah County, Utah. This is the same formation that is famous for producing well preserved fish fossils, but a different member and location.
