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
An organism that has a hard structure is most likely to become a  fossil because it can survive through different weather changes and  an organism with a soft structure willâ¦ most likely dissolve or  decompose.  +++  Partly right. The soft tissues decompose leaving shells or  bones, which are not very soluble.
