mastodon vs. mammoth: What’s the difference?

Mastodons and mammoths—both now extinct—were both huge, hairy, elephantlike mammals with tusks. Some lived at the same time, flourishing during the Pleistocene Epoch. However, the two belonged to different genuses, and mammoths were bigger. Mastodons went extinct around 13,000 years ago. Most mammoths went extinct around 10,000 years ago, but some lived until around 4,000 years ago.
