They were covered in a thick coat of brown hair to keep them warm in their home on the frigid Arctic plains. They even had fur-lined ears. Their large, curved tusks may have been used for fighting. They also may have been used as a digging tool for foraging meals of shrubs, grasses, roots and other small plants from under the snow.
Though woolly mammoths went extinct around 10, years ago, humans know quite a bit about them because of where they lived. The permafrost of the Arctic preserved many woolly mammoth bodies almost intact. When the ground around riverbanks and streams erodes, it often reveals the corpse of a long-dead mammoth that looks much like it did when it died. For example, in in Siberia, a pair of mummified baby mammoths were found.
He put the tusks in the wrong sockets, so that they curved outward instead of inward. Preserved mammoth hair looks orange in color, however researchers believe the pigment was changed because of prolonged burial in the ground. Even a kid can discover a preserved mammoth. The remains were of a year-old male woolly mammoth that died about 30, years ago. The final resting place of woolly mammoths was Wrangel Island in the Arctic. Although, most of the woolly mammoth population died out by 10, years ago, a small population of woolly mammoths lived on Wrangel Island until BC.
For context, Egyptian pharoahs were midway through their empire and it was about years after the Giza pyramids were built. The reason for the demise of these woolly mammoths are unknown.

Remarkably, they managed to survive on small Arctic islands off northern Siberia until around 4, years ago. The long, curved tusks of woolly mammoths are probably the most immediately recognized ice age fossil from Yukon.
A single tusk from an adult male can stretch over 3. These tusks may have been used for display, defense, or possibly to sweep away snow to get at grass in the winter.
Tusks preserve a wealth of information about a mammoth's life because they are a lot like trees, with layer upon layer of growth rings forming over time. By studying these growth rings, scientists can learn about a mammoth's health through its entire lifespan, the climate it lived in, and where it migrated to and from. Mammoth teeth, or molars, are common fossils in Yukon.
