    Hopefully someone can tell me what this is. I have no idea.

      This is a piece of chert (AKA flint). The circular hole in the last two photos might have been the impression of a crinoid (AKA sea lilly) stem, but given it’s worn state it is hard to tell. Otherwise, there does not appear to be any fossils in this rock.
