Fossilized bones?

This was found in my backyard in Waco, Texas. Its heavy, has petroglyphs and bones. Looks like a human skull. Strangest thing is there is piece of metal embedded in it.

Ok, it looks like a chunk of limestone, I'm sure it is heavy, it is a rock.  I do not really see a resemblance to a human skull.  Petroglyphs?  Please point out what you are seeing.  Where is the metal, I can not pick it out in your pictures.

Also please point out the bones you see and a clue to the size of this.

Looks like a chert nodule, to me. No bones, or bone texture. Not seeing any petroglyphs or metal, either.

  This is what many of us would call a rock.  Sorry
