Fossil Birch "Cone" (Betulas) - Green River Formation, Colorado

This is a fossil birch "cone" (Betulas sp.) from the Green River Formation of Colorado. It shows dark color preservation that contrasts nicely against the cream colored shale. While the Green River Formation is best know for its fish fossils, other areas produce incredible plant fossils.

It comes with an acrylic display stand.

There are repaired cracks through the rock where the shale shattered during collection.
