Interestingly, the Wooly Mammoth (Mammuthus primigenius) had 6 sets of teeth throughout its lifetime, which were progressively larger. They are designated as P2, P3, and P4 for juveniles and M1, M2, and M3 for adults.

Woolly mammoths are iconic Ice Age animals. Great herds of mammoths roamed the steppes of the Northern Hemisphere, with populations extending from the British Isles, through Siberia, and into North America. They were impressively large, reaching 11 feet tall at the shoulders and weighing up to 6 tonnes. Their tusks were larger and more curved than modern elephants, reaching up 13.5 feet in length!

Woolly mammoths had many adaptations to a cold environment, most notably a dense fur coat. Furthermore, their ears and tails were short to prevent frostbite and heat loss. They also had very specialized teeth. High-crowned molars were well suited to grinding tough, fibrous steppe grass.
