Answer
The predatory nature of the animal may not directly contribute to fossilisation. Predatory animals may have a higher risk of being consumed by other scavengers before they can be fossilised.
Step 2
B. the action of waves and currents.

Answer
Waves and currents can lead to the erosion of sediments but can also facilitate the burial of remains, which is crucial for fossilisation. However, excessive movement may disturb the remains, making this factor not crucial for the process.
Step 3
C. the salt content of the water in which it lived.

Answer
The salt content of the water could affect the type of sediments present and the preservation of the remains. Higher salinity can sometimes enhance preservation due to reduced bacterial activity.
Step 4
D. its hard-plated mouth and spiny appendages.

Answer
The hard-plated mouth and spiny appendages of the animal likely aided in its survival. These hard structures are more likely to fossilise because hard parts are generally better preserved in the fossil record.
