Giant sloth vs. ancient man: fossil footprints track prehistoric hunt

Scientists have uncovered evidence of ancient humans engaged in a deadly face-off with a giant sloth, showing for the first time how our ancestors might have tackled such a formidable prey. Standing over 2 meters tall, with forelegs tipped with claws, giant sloths lived until around 11,000 years ago. Most scientists believe over-hunting by humans eventually led to their extinction.
