Four conditions for fossilization:
Only dead organism or plant
The dead to be buried quickly
Prevention of decaying and decomposition of the dead
Dead to be buried in environment where carbonates precipitate at large
Explanation:
The plants or animals preserved in sedimentation rock are said to fossilized and the process is called fossilization.
Conditions for fossilization are:
1) Only dead organism or plant: Only dead animal or organism are considered for fossilization.
2) The dead to be buried quickly: To preserve the organism a death by natural calamity is best.
3) Prevention of decaying and decomposition of the dead: The animal needs to be kept in anaerobic conditions and ensured that bacteria do not throng and start the decaying process.
4) Dead to be buried in environment where carbonates precipitate at large:
The soil should be rich in mineral rich water in which carbonates are in excess. The carbonates will get deposited on the degrading tissues and the tissue attain the shape of rock formed by carbonates.
