Collagen from bone was prepared by several methods. For modern and well-preserved bone
the δ 13 C and δ 15 N of collagen replicas obtained after HCl or EDTA demineralization …

Empirical observations of δ 15 N of bone collagen by age at death from 56 archaeological

We used the natural abundance of stable isotopes (carbon and hydrogen) in the feathers of
a neotropical migrant songbird to determine where birds from particular breeding areas …

The biomineral component of bones and teeth is synthesized within the body, under direct
physiological control, and therefore the chemistry of bone (including the trace element …

The amount of DNA in ancient bone was determined by ethidium bromide staining after the
