    This class of techniques has a nominal range from the present to several hundred thousand years. They depend on the essential insolubility of

    web search doesn't find any discussion of the magnitude of this - I
    imagine a 19th century sample being dated as pre-Columbian). As is
    obvious the method depends on the sample being from a chemically closed system - consequently uranium leaching is a known issue.


    When Bing CoPilot woke up I asked it about this. It agrees with me, but
    fails to provide citations, even when prompted with a second question.

    It's pretty easy to suggest a reasonable explanation that could
    be readily tested. A brief review of the web fails to find
    documentation from tests performed.

    The consensus seems to be that it looks very much like a type
    of mining hammer what was in use in Texas (where it was found).
    The design is consistent with other mining hammers used in the
    early 1800s. There are similar artifacts known to be mining
    hammers in existence.

    Two obvious things to test would be the iron in the hammer head
    and the wooden shaft. I'd suggest metallurgical testing of the
    atomic composition of the head including isotopic analysis to
    be compared with a range of other artifacts known to have been
    used in Texas, and of course comparison to a range of iron
    artifacts from other sites around the world and other times.

    Special note: if anyone tries to make a claim about C14 in the
    hammer head they are a complete moron.

    I would however test the haft to determine the species of wood
    and a C14 date. Special care is needed when doing that date
    because the artifact is likely to be partially mineralized with
    contamination from the limestone that feed the concretion that
    it appears to be embedded in. The carbon in the limestone is
    of course a distinct source of carbon from the wood of the shaft.
    And of course the carbon in the limestone will be older than
    a range relevant to C14 dating.

    I can't help but notice that the haft is broken, much like a
    mining hammer haft would break.

    So ultimately, I speculate it is a mining hammer from the
    early 1800s that was broken and discarded in an active limestone
    cave. The active cave subsequently produced a concretion that
    enclosed the broken hammer. Concretions can form rapidly in
    active caves. They are what stalactites and stalagmites are.

    I'm not well versed in how to test the age of concretions but
    there are likely ways. It would be best to know exactly where
    the hammer was found so tests could also be made on the surrounding
    limestone sources.

    I will add that the fact that none of this, or perhaps better
    alternative testing, has apparently be done suggests that the
    keepers of this artifact are more interested in marketing a
    manufactured controversy than in understanding it.

    Good summation; thanks. As an aside, be prepared to have any
    "response" from JTEM the Incredible Bore to truncate your
    post to one or two lines (or less) and ignore what you
    wrote.

    And to the broader audience, yes, I know. But this isn't
    Purina Troll Chow as it lacks the essential invectives.

    Invective is not, strictly speaking, required, but it *does*
    tend to generate more responses.

    I believe an explanation can be found in a prophecy from the Book of
    Brian: "At this time, a friend shall lose his friend's hammer, and the
    young shall not know where lieth the things possessed by their fathers
    that their fathers put there only just the night before, about eight o'clock."

    Is that daylight saving time?
