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
In living organisms, the ratio of the naturally occurring isotopes of carbon, C-12 to C-13 to C-14, is fairly. consistent. When an organism such as a woolly mammoth died, it stopped taking in carbon, and the. amount of C-14 present in the mammoth began to decrease.
