The London Artifact:

There has been much controversy over the excavations in the Paluxy riverbed in Glen Rose, Texas.  Over the years there have been several groups and individuals who claimed to have found human footprints alongside, and in, the already famous dinosaur tracks of the Paluxy.

If it can be demonstrated that humans and dinosaurs co-existed in the fossil record, this would exactly contradict the theory of evolution, demonstrably falsifying it.  It is understandable why one should be cautious and skeptical of claims such as human and dinosaur tracks found together, however it should be noted that this is not the only evidence of their contemporaneous existence that has been found.

The London Artifact is a hammer, probably used for fine metal working judging by its size, weight and the ends of the head.  It was found near London, Texas, near a waterfall in 1934.  The rock of this area is dated geologically as Cretaceous (144 Million to 65 Million years old), or during the time of the dinosaurs.  Besides being a fascinating find, the metallurgy of the hammer is remarkable:  Good, high quality metal with no bubbles or slag and a bizarre compounding of 96% iron, 2.6% chlorine and 0.74% sulfur.  A cut was made into the corner of the head to verify it was metal.  Sixty years later, that cut (shown also on this replica) has still not rusted!  When you compound chlorine with iron you get a powder etchant - not tough steel!
