Hey ✌️

Molds and casts are three-dimensional impressions in which the surface contours of an organism are preserved. Organisms buried in sediment slowly decompose, leaving a cavity that contains an exact imprint of the organisms shape and size.

Bones are is preserved in cast and mold fossils.

Explanation:

Normally the other ‘parts of the body’ like muscles, ligaments, blood and organs are soft.

So they can be easily degraded by the presence of microorganisms and their enzymes.

Hence they act to recycle the nutrients in the ecosystem. On the other hand bones are very strong body part, and are rich in calcium and phosphorus which gives some resistance to be degraded.

They turn into fossils since they take a long time to get defeated.
