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
Male mammoths were more adventurous than female mammoths, especially when they were teenagers. At this site, several lone male mammoths got caught in a sinkhole and died, one by one over a long period of time. Fossil sites like this one, show us that mammoth males wandered on their own. Paleontologists have also found mammoth trackways that include the footprints of several mammoths walking side by side.
