A lepidodendron fossil
A dark brown rock with scale like ridges stands out on a light tan rock. The scales are distinct and large.


A lepidodendron was a tree that originated during the Pennsylvanian Age (about 318 million years ago). While these fossils originated during the time when Pangea (the last supercontinent) existed they are now spread out all over the globe, mostly in western Europe and eastern China.Lepidodendron, also called “Scale Trees”, are characterized by scale like bark and widespread root systems. They would grow to be about 100 feet tall and 7 feet wide. More info: Uncovering the Fossil Record of Buffalo National River (U.S. National Park Service) (
