Possible Mineral Concretion

In contrast to the ancient dating, some experts said the London Hammer looks like typical American tools manufactured in the Texas region in late 1800s. Moreover, Geologists suggested it is possible Highly Soluble Minerals in the Ancient Limestone formed a Concretion around the Hammer. Concretions are masses of hardened mineral matter, which can form fairly quickly around objects. So, this does not make the object inside as old as the mineral matter is. NCSE (National Center for Science Education) researcher John Cole described that minerals dissolved from ancient strata can harden around a recent object, making it look impressive to someone not familiar with geological processes. He also suggested the London Hammer was probably a 19th Century Miner’s hammer.

So, the stories claiming to show the London Hammer is more than 400 million years old are not true. Probably, a local miner or craftsman dropped or discarded the hammer in the last few hundred years. Later, dissolved limy sediment could have hardened into a nodule around it.
