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
Scientists may have figured out why the woolly mammoth became extinct. A new study of the prehistoric beasts suggests they might have been wiped out after the last Ice Age. There's evidence that humans hunted mammoths and it was previously thought the mammoth may have driven to extinction by hunters. But scientists analysed the dozens of mammoth fossils and now think rising temperatures melting the mammoths' habitat drove them to extinction.
