1. Ice Age Cousins: Mastodons were massive, furry relatives of modern elephants and woolly mammoths that roamed North and Central America during the Ice Age!

2. Not a Mammoth: Even though people often mix them up, mastodons and woolly mammoths were actually quite different! Mastodons were slightly shorter and stockier, and they had flatter heads.

3. Forest Munchers: While woolly mammoths loved grazing on wide-open grassy plains, mastodons preferred hanging out in forests and swamps, using their tusks to pull down tree branches, twigs, and leaves.

4. Cone-Shaped Teeth: Mastodons get their name from their unique teeth! The word "mastodon" comes from Greek words meaning "nipple-tooth" because their molars had bumpy, cone-shaped points designed for crushing hard leaves and twigs.

5. Curved Tusk Power: Like their mammoth cousins, mastodons had enormous, curved tusks. Some of these ivory tusks could grow up to 9 feet long and curved upward.

6. Heavy Coats: Because they lived during freezing Ice Age winters, mastodons wore thick, shaggy coats of coarse brown hair to keep themselves warm against the snow and ice.

7. Ice Age Neighbors: Mastodons lived alongside other incredible ancient animals like saber-toothed cats, giant ground sloths, and early humans before they vanished about 10,000 years ago.
