Charlie, with all due respect, your reply is why these discussions degrade to mud slinging. you bring up the wharf sign so you can "make a point". the fact is, that has nothing to do with anything. I am happy to discuss things, but no desire to sling mud. sorry if I seem pissy.
now, as to the bones, it seems odd that the only pieces of bone found have been with a drill in the manner described. to my knowledge, the only bone material found. which is more likely, the only two fragments of bone discovered, migrate there way down a shaft only to be extracted by the same drill, or the drill picked them up there. two bits of bone migrated together, at the same time, and end up in the same place?
