The rate at which bone decays is very variable and depends on many different factors. Human bone is often preserved for very long periods due to the fact we bury our dead. This protects the bones from sunlight, wild animals, weathering and other factors which normally make bone break down. Bone may decay in a period as short as 10-20 years.
