JEFFERSON’S GROUND SLOTH
Today, modern sloths are seen as semi-comical creatures: small, slow, and harmless. But the Jefferson’s ground sloth was an ice-age giant — as long as three metres and around a thousand kilograms in weight. With its peg-like teeth, the sloth feasted on leaves and other plants — but its long and sharp claws offered serious protection against predators. The Jefferson’s sloth was not the largest of the prehistoric sloths, but with its thick fur coat it was the best-adapted for the colder climate of northern North America.
