content: Most likely no. Most skeletal fossils, particularly dinosaurs, are no longer bone, but rather sediment and minerals. The organic parts of the bone (Marrow for example) rot away and disintegrate, but the minerals in the bone (Calcium and iron comes to mind) stay behind and are mixed in with minerals from the surroundings soil to create what is essentially a rock. However  i'd recommended you look it up online somewhere to fact check me, all I can be certain of is that fossilized bones are hardly ever bones as we think of them.
