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 woolly mammoth is considered to have had the most complex molars of any elephant. Distortion in the molars is the most common health problem found in woolly mammoth fossils. Sometimes the replacement was disrupted, and the molars were pushed into abnormal positions, but some animals are known to have survived this.
