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
Mammoths may have formed large herds more often, since animals that live in open areas are more likely to do this than those in forested areas. Trackways made by a woolly mammoth herd 11,300â11,000 years ago have been found in the St. Mary Reservoir in Canada, showing that there were in this case almost equal numbers of adults, sub-adults and juveniles.
