As you can see, the top of the tooth is flat. This is because the mammoths grind their food causing the top of the tooth to flatten out. Mammoth teeth were specially adapted to help mammoths survive. The teeth are strong and resistant to wear which was important because mammoths ate mostly grass. Grass is very hard to eat because it contains silica, which on a tooth that wasn't as strong as the mammoths, would rub the tooth like sandpaper.
Paleontologists often find teeth from extinct animals.
This is because the enamel coating makes them less resistant to decay. Mammoth teeth are found all over the world. Usually, teeth are found in areas that were covered by savannas, grasslands, and tundra during the last ice age. If you look at the tooth closely, you can see that the tooth is more worn on one side. Mammoths and mastodons are distant cousins.
