title: X-ray microanalysis of fossil dinosaur bone: age differences in lead, iron, and magnesium content.
abstract: Bones of dinosaurs, Gallimimus bullatus, belonging to selected age groups, were studied using an X-ray microanalyser. The content of lead, iron, and magnesium, as well as the distribution of those elements in the investigated bone areas were determined. The results showed, that bones of old animals contained the highest level of lead and iron, whereas in young dinosaurs the respective values were lowest. The obtained data were compared with the results of X-ray microanalysis of the contemporary bone.
