Hello all. I am no expert, just curious. I visited Greenbrier County West Virginia last July and picked up a few rocks along the banks of the Greenbrier River. After inspecting this one, I found what appears to be scales along its surface and a foot (arrow pointing). I have a lepidodendron root my uncle gave me the 1980s and it made me interested in fossils, just wondering if anyone can tell me what I’m looking at. Either way it’s a pretty neat find for me. If I should post more pictures, let me know. Thanks for any and all help!
