Giant Bull (Mammut americanum)

Enormous mammoths and mastodons roamed North America in the Ice Age, and humans hunted both. The “American Mastodon,” Mammut americanum, was the last species of Mammut and kept the same simple chopping molars that had evolved in the Miocene 12 million years earlier. Different dietary preferences keep mastodons and mammoths apart in most places. Mammoths preferred grass and dry leaves in open plains and woodlands while Mastodons went for softer, wider branches in wetter forests and swamps. Many mastodon bones turned up in bogs being drained by American farmers in 1700s.
