Today’s Fact: Why bones survive?

Hey guys here is new amazing and interesting fact for you all

Why bones survive????

You probably think that a person’s bones disintegrate soon after death. In fact, bones are quiet resistant to decay.

Archaeologists – scientists who study past cultures by digging up ancient towns cities – sometimes find human skeletons that are very well preserved. This is because human bones are mostly composed of two minerals: calcium and phosphorus. Bones are extremely strong and remain relatively intact for a long time after the surrounding tissue has decayed.

Not all parts of the skeleton are preserved equally as well. The skull and lower jaw usually survive longest. Other bones which are found well preserved are the long bones of the limbs, the ribs and the hip bone.
