A mammoth is more likely to fossilize than a caterpillar because a caterpillar has no hard tissue. Bones and cartilage are much more likely to fossilize.
Not all organisms are preserved as fossils because the conditions required for fossilization are rare. Factors such as rapid burial, absence of oxygen, and the presence of minerals must align to preserve an organism as a fossil. Additionally, the soft tissues of organisms often decay before they can be fossilized.
To scare. Or to fossilize.
Bones typically fossilize the most. There are some examples of fossilized feathers and hair, but it's rare.
Amber is lithified tree sap. Small insects and animals can be preserved but not fossilised in amber.

They don't decompose at the right rate or at the right place or at the right temperature.
No, there are certain materials that can't be Fossilized
A clam.
A fox would be the most likely. A moth is smaller, and therefore would take less time to decompose. However, for anything to(technically) fossilize takes a very long time
mainly high pressure but you'll also need sediment such as rock or sand to smash it and as the soft parts of the plant decay they leave impressions on the rock
If you mean fossilize, it means that something has been lying in the ground for so long that it has become a fossil; usually refers to ancient bones or plants.
