This curious artefact was found in London, Texas, USA in 1934. The hammer was embedded in the rock and has been many theories about its origin, and most importantly its incredible age.

So how did the hammer end up being stuck in the rock? Well, to finish the hammer inside the rock it had to be built before the rock was formed and which was several million years ago.

After their discovery and all the questions raised by the hammer, the researchers decided to abandon the unbelievable discovery at the Somervell Museum in Texas.

The internal handle underwent the process of carbonization based on studies by the Metallurgical Institute of Columbia and the hammerhead was built with iron purity only achievable with modern-day technology.

According to analysis, the head of the hammer consists of 97 pure iron, 2 per cent chlorine and 1 per cent sulfur. Surprisingly researchers also found that the iron had undergone a process of purification and hardening, typical of the metallurgy of the twentieth century.

According to analysis, the rock encasing of the hammer was dated to the Ordovician era, more than 400 million years ago.

The portion of stone surrounding the hammerhead also presented abnormalities, seeming to have merged with some type of sheath covering the hammer. According to geologists, the slow process of petrification dates back hundreds of millions of years.

This has led several ufologists and ancient astronaut theorists to a quick deduction of the context of the incredible discovery leading them to assume not only that there was a human civilization before the historical process of petrification in Texas, but that this ancient civilization already possessed the necessary technology for the fabrication of a hammer with modern features.

Evidence suggesting that the iron from the hammer might have originated from a meteorite is not a possibility according to researchers. The chemical analysis of the artefact also detected certain amounts of potassium, silicon, chlorine, calcium and sulfur.

Thus, this composition contradicts the hypothesis postulated that the hammerhead belonged to the fragment of a meteorite since the bodies of our solar system do not have that type of chemical composition.

Researchers also believe, that since the head of the hammer was found embedded into the rock, it suggests that the embedding process was performed under different atmospheric conditions to the current, different atmospheric pressure, more similar to those in the remote past.

Against the remote possibility that a meteorite with extremely rare and bizarre chemical composition and exceptional morphology, got caught, in prehistoric times, onto a piece of wood just as the head of the discovered hammer imprisons its handle, some researchers and ancient astronaut theorists point toward the fact that our planet was inhabited in ancient times, by civilizations with advanced technical and technological capacity, of which today we only have legends and items like this one who were trapped in the rock.

Unfortunately, some scientists do not agree with the theory that an ancient civilization created the hammer, and claim that it was only a metallurgical technique that had been eventually abandoned.

This extraordinary artefact belongs to the list of many other mysterious objects that have been discovered across the globe, and just like the Russian “microchip” or the 300 million-year-old screw, this item has caused debate among researchers and historians who are divided into groups, supporting and denying the possibility that the human race is much older than previously thought.

Whether this artefact is indeed a hammer dating back hundreds of millions of years, is something that will fuel debate among supporters of the ancient astronaut theory and conventional archaeologists, who both have provided arguments explaining the origin and age of the hammer.
