Small mammals were alive when dinosaurs roamed the earth. No one is quite certain why dinosaurs died out. Some scientists

Creature of the Ice Age
There were Ice Ages which lasted for 200,000 years. When this happened the earth was covered with a coat of ice. Plants did grow and the woolly mammoth was able to feed on them. The temperatures were very low, however. To overcome these conditions the woolly mammoth developed a very thick coat of hair. It was a long shaggy coat. To keep the animal warm in these very cold conditions, there were two layers to the coat.
Where did they live?
The remains of the woolly mammoth

How do we know about the mammoth?
We know about most of the animals which lived in the past because of the fossil remains which have been found. Much of what has been written and drawn has been pieced together. There has also been a great deal of guesswork. In the case of the woolly mammoth the situation is different. Although much of the ice disappeared at the end of the last Ice Age, there were still parts of the world which were very cold. They have been very cold since that time. During the Ice Age, mammoths died and were trapped in the ice. The ice has preserved them. Instead of just having bones to examine, as we do with most extinct creatures, whole mammoths have been discovered. With most prehistoric animals we have to guess what the skin looked like. It is very different with the woolly mammoth. Because whole animals have been preserved, we can look at the hair and tusks. In fact, we can look at the entire body.
What did they eat?
Although they were large creatures, woolly mammoths fed on plants. They ate willow, fir, and alder leaves. They also ate the leaves from bushes. We know what the woolly mammoth ate because complete dead animals have been found in Siberia. When the stomach contents were examined many different kinds of leaves were found. Woolly mammoths probably used their tusks to clear snow from the ground so they could get at their food.
What was the earliest elephant like?

Why did the mammoth become extinct?
No one is quite sure why woolly mammoths became extinct. Various suggestions have been made. It could have been due to changes in the climate. When the woolly mammoth lived it was during one of the Ice Ages. The ice gradually melted and the earth got warmer. This change could have affected the woolly mammoth. Man also appeared on the scene. He might have hunted and killed the creature. It is also likely that man moved into the places where mammoths had lived. Man would have used some of their feeding grounds to grow his crops. The woolly mammoths would have been driven out with no where to go.
