Close up of the exposed wood:
Random picture from a search of what it should look like out of the exposed earth:
I've had this one at least two years and it was found directly within the tidal area. It's notably dried and fractured in that time. Probably should coat it with clear nail polish (edit: I did it chat.). I have more fully encased (it's in the pic above with 3 pcs) but have not got around to ordering more polish lol.
You can find pyrite fossils in Pennsylvania as well, surprisingly.
