Re: Sauropod necks????

Yes, I presume that the presence of soft tissue proteins (or at least, of
amino acids) would be a requirement.  Totally replaced bones wouldn't
work.  OTOH, isotopic studies of nitrogen and carbon have been conducted
on fossil vert. bones, so this proceedure isn't exactly unheard of in
