A belemnite swimming in the sea during the Jurassic period.
The carcass decomposes.
Eventually only the hard internal skeleton is left.
Mud sweeps into the sea, which buries the belemnite.
The belemnite becomes deeply buried over millions of years.
The belemnite becomes partly crushed and delicate areas dissolve leaving only the harder parts as mineral remains.
