Age: Eocene
Formation: Green River Formation
Location: Bonanza, Utah

Here is an extremely rare leaf from Utah. This is Symphoricarpus sp. (Snowberry) from the Green River Formation. This is the only example of this leaf that we have ever seen from this site. The fossil Snowberry leaf has a very rounded shape and exhibits fine detail. The entire, slightly undulating margins of the leaf are intact. This leaf has strong primary venation and much weaker secondary and tertiary venation. Under magnification, however, the tertiary venation is easily seen forming a fine network of capillaries. The dark-colored leaf contrasts beautifully with the grayish-tan matrix. It is nicely positioned on the squared plate of shale. This is an excellent example of this very scarce leaf from the Eocene.
