This was in a lump of coal, not just in the seam.
I don't know. How you YOU explain how it got there when you claim the lump predated man by 300 million years?
In June 1936... 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. The hammers head, made of more than 96% iron, is far more pure than anything nature could have achieved without an assist from modern technology....
In 1944, as a ten year old boy, Newton Anderson dropped a lump of coal in his basement and found that it contained this bell inside. The bituminous coal that was mined near his house in Upshur County West Virginia is supposed to be about 300 million years old! What is a brass bell with an iron clapper doing in coal ascribed to the Carboniferous Period?
