The Teeth of the Woolly Mammoth

Mammoth teeth are rather interesting and distinct, as they are made up of a set of compressed enamel plates held together with what is called cementum. The cemented plates create a very strong, tall tooth that is resistant to wear and tear. The tooth first breaks through the gum cavity, which the mammoth will use to grind the coarse texture of their diet ”“ vegetation and grass. The tooth develops a flat top with low enamel ridges where the plates suffered wear as a result of this action. The mammoths relied greatly on their teeth to consume their diet. The grass was very difficult to eat because it was comprised of small pieces of silica (a glass-like substance) in its leaves. The silica bits would act in the same manner as sandpaper grit ”“ wearing away anything that was less resistant to the material.

Mammoths in North America

The first mammoths entered North America around 1.5 to 1.8 million years ago. The creatures migrated from Eurasia ”“ crossing the Bering Strait during a time period where the sea level was lower than it is today. The first mammoths were part of a species known as M. meridionalis. Descendents that came from this species of mammoth includes the Columbian and Jefferson’s mammoths. The woolly mammoths from Eurasia used the Bering Straight to reach North America at a much later time. Scientists believe it may have been sometime less than 500,000 years ago. Unfortunately, about 11,000 years ago ”“ all of the species of mammoths were extinct in North America.
