A petrified hammer was found in Cretaceous rocks
Every once in a while archaeologists (and sometimes regular Joes) make some remarkable discoveries. Stunned, they are often unable to explain what it is they’ve found, how it came into existence, or ascertain its value. This is a comprehensive list of such artifacts; artifacts that many believe should have never existed given the discerned age/period of their creation.
In June 1936 (or 1934 according to some accounts), Max Hahn and his wife Emma were on a walk when they noticed a rock with wood protruding from its core. They decided to take the oddity home and later cracked it open with a hammer and a chisel. Ironically, what they found within seemed to be an archaic hammer of sorts. A team of archaeologists checked it, and as it turns out, the rock encasing the hammer was dated back more than 400 million year; the hammer itself turned out to be more than 500 million years old. Additionally, a section of the handle has begun the transformation to coal. Creationists, of course, were all over this. The hammer’s head, made of more than 96% iron, is far more pure than anything nature could have achieved without an assist from modern technology.

An iron hammer with wooden handle was found embedded in rock in Cretaceous sediments (or Ordovician, by some accounts) near London, Texas. The enclosing rock contains Lower Cretaceous fossils.
While this has fallen out of favor with most creation scientists there is one aspect of this hammer that suggest that this could still be Pre-Flood. Those who insist that this hammer is recent have yet to offer an explanation for it. The iron head of the hammer has a coating of FeO which needs two atmospheres of pressure to form. There may be another answer other than the hammer being pre-Flood but nothing has been proposed as of yet.
