X-ray microanalysis of fossil dinosaur bone: age differences in the calcium and phosphorus content of Gallimimus bullatus bones.
Bones of dinosaurs, Gallimimus bullatus, belonging to selected age groups were studied using an X-ray microanalyser. Content of calcium and phosphorus, their distribution in the investigated areas and Ca/P ratio were determined. The obtained results revealed that the Ca/P ratio highest in the bones of young and middle-aged animals and decreased with age.
