*THIS IS DOUBLE SIDED* These amazing self-collected fossilized leaves are from the Late Eocene - Early Oligocene time period. There is some debate on which formation they are coming from as we are finding mixed information from different geologic surveys and maps. These leaf fossils are from the beautiful State of Washington. We believe these fossils are 33 million - 23 million years old. On this slab in particular, there are a lot of different kinds of fossil flora. Atleast 3 different types of leaves and some other plant material. We believe the species of the fossil on the back side is a willow leaf from millions of years ago.
