Re: fossils stick to tongue?

Has anyone heard that certain types of fossil bone stick to one's tongue? If so, what is the mineral that would produce this phenomenon? talc?

Many thanks in advance for advice!

I have read that calcium is the mineral in question. Apparently if the bone is young enough to have some calcium in it, it will stick to your tongue. An old bone (more than 50,00 years or so) with all the calcium gone will not stick.
