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
The larva, or caterpillar, that hatches from the egg is the second stage in the life cycle. Caterpillars often, but not always, have several pairs of true legs, along with several pairs of false legs or prolegs. A caterpillar's primary activity is eating. They have a voracious appetite and eat almost constantly.
