Why is a mammoth more likely to fossilize than a caterpillar? 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. Edit
When this happens they molt, splitting the skin and crawling out of it. Caterpillars may shed their skins four or five times in this second stage of the life cycle. In the third stage the caterpillar goes into a resting state and is called a pupa. Different caterpillars pupate in different ways. For example, many moth caterpillars burrow into the ground; others hide behind loose bark or in hollow logs.
