In Which Rock Strata Is Coal Found

  • London Hammer - Wikipedia

    The London Hammer (also known as the "London Artifact") is a name given to a hammer made of iron and wood that was found in London, Texas in 1936. Part of the hammer is embedded in a limey rock concretion, leading to it being regarded by some as an anomalous artifact, asking how a man-made tool could come to be encased in a 400 million year old rock.
