Among my first posts here was a piece that I initially thought was some kind of coral, but those who reviewed it thought it may have been Lepidodendron Stigmaria, although still puzzled by its appearance. After countless times of looking it up, I've yet to see any Lepidodendron fossils (root or not) that look quite like it. I was reading up on fossils again recently and came across another Pennsylvanian fossil (related to Lepidodendron) that, in my opinion, looks far more like my specimen.
