@matthew-gramling@aneta-hulist I’m leaning more towards bryozoan. While there are Lepidodendron with hexagonal leaf bases it seems smaller than normal. I would also expect to see a xylem and parynchnos scar although those could just be covered by sediment.

Greetings @aneta-hulist ! I have to concur with @a-trilobite with the potential scale tree ID. @mackenzie-smith might be able to comfirm.
