Columbian mammoths had impressive, spiralled tusks that measured up to 4.9m, making them world record holders amongst the elephant family. There is some debate as to how hairy Columbian mammoths were and some scientists suggest that they had a full fur coat, like the woolly mammoth's. It is more likely that hair grew more extensively on some parts of the body, such as the top of the head, but that they were basically elephant-like with exposed greyish skin. Columbian mammoths ranged through the southern half of North America and south into Mexico before becoming extinct approximately 12,500 years ago.
