Answer
Slow burial in dry sediment does not significantly increase the chance of fossilization. In fact, slow burial can lead to decomposition before fossilization occurs.
Step 2
b. large temperature variations in the sediment containing its remains.

Answer
Large temperature variations are generally not conducive to fossilization as they can lead to rapid decay and disruption of the remains.
Step 3
c. the presence of hard body parts.

Answer
The presence of hard body parts significantly increases the chance of fossilization. Hard parts, such as shells or exoskeletons, are more likely to be preserved than soft tissues.
Step 4
d. the presence of scavengers at the time of its death.

Answer
The presence of scavengers at the time of death decreases the chance of fossilization, as scavengers consume the remains before they can be buried and preserved.
