How did mammoths stay warm?

Mammoths, like their elephant cousins of today, would have been adapted to the warm climate they evolved in. In these climates, an elephant’s biggest problem is getting rid of heat — they do this with their big ears, through which many heat-porting blood vessels circulate.

Are mammoth warm blooded?

Why did Woolly mammoths have dark fur?

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. The permafrost of the Arctic preserved many woolly mammoth bodies almost intact.
