two things- fossilization where they are fossilized for millions of years and bones don't rot.
They take magnesium.
Depends on the animal- there is no one answer. Unless you want to say that ALL bones are in animals.
limestone is made underwater from the shells of animals. We know this because limestone also contains many fossils.
nine million animals de a year from broken bones.

Aniamls with solid substances in their body can be easily preserved in the right conditions and dug up many years later like all the dinosaurs we've found, for example. However, animals like jellyfish that don't have bones in their body are more likely to be preserved like leaves, that are molded into the dirt.
