Hammer found in Cretaceous layer

Why wouldn't it? Explosions in coal mines result in extreme heat production, collapse, and pressure. How is that not a viable explanation for the 'cup' being encased in coal?

The thing is, we don't know that it looked like normal coal. I have heard many things from laymen only to be disapppointed by the reality. A trained and experienced person should be able to tell the difference, but as yet, I do not see anything that would lead me to believe this instance of a buried artifact. The picture is less than convincing. Where is the mold that the affidavit mentions?

If the hammer was lost in the 19th Century and trapped in a concretion between then and the time it was found then it isn't a fake. But it isn't evidence of creation either.

Well the hammer looks like a 19th Century hammer. The condition would be surprisingly good for something even thousands of year old (wood usually rots except in unusual conditions) and the supposed carbon date is consistent with a 19th century origin. So really it's worth asking what evidence is there that it is anything older ?

As to the other finds, the "finger" certainly isn't a fossil finger.
