No, they are biodegradable. So far, there has been no "bones" recovered from the Titanic wreck site as all the bones are now dissolved in the sea water or eaten by various sea organisms. The same happens over time in the earth.
In some special cases the bones mineralize by replacing their structure with other inorganic materials. these fossilized bones last a long time.
THE TWO KINDS OF WASTE ARE THE BIODEGRADABLE AND NON-BIODEGRADABLE BIODEGRADABLE WASTE THAT ARE DECAYING NON-BIODEGRADABLE WASTE THAT WILL NOT DECAY AS TIME PASS
A cloth bag is an example of non-biodegradable waste.
biodegradable
Biodegradable waste is a type of waste which can rot and change into manure. Non-biodegradable waste is a type of waste which cannot rot and change into manure. Such waste piles up and causes pollution. There is no way of destroying it except for burning it, which further pollutes the atmosphere.

why is waste for us

non-biodegradable
Biodegradable waste is a type of waste, typically originating from plant or animal sources, which may be broken down by other living organisms. Waste that cannot be broken down by other living organisms may be called non-biodegradable. Biodegradable waste can be commonly found in municipal solid waste (sometimes called biodegradable municipal waste, or BMW) as green waste, food waste, paper waste, and biodegradable plastics. Other biodegradable wastes include human waste, manure, sewage and slaughterhouse waste.
