ok, we went to a local university today. The geology professor thought I needed another opinion on the rock. He said "it is the strangest chert nodule I have ever seen" "There is a 5% chance you are right about it being a fossilized head" "I do not know" "it does look like bone". "I do not understand how it could have formed" "That fine sheen on the top is very strange." "we do not know what makes silica concentrate into flint"
He also ran some tests, and interestingly, the "teeth" did not react to acid - while other white calcite on the stone did.
Woo hoo! I am still trying to be disproved.
'on my way to higher ups in the next few days!
