In this episode, we will dive into fossils.

Fossils, remains of ancient life, are preserved in rocks through natural processes. These formations occur through various methods. 

One method involves soft materials hardening, leaving behind casts like footprints.

Alternatively, preservation happens where decomposition is hindered, such as in glaciers or peat bogs. 

Another means involves mineral replacement, where hard body parts gradually transform into rock-like structures. 

The resulting mineralised structure of something like a tooth then remains distinct within the surrounding rock.
