Sloth's Didn't Use To Look Cute and Cuddly

Scientists have discovered fossil footprints that may prove ancient humans faced off with a giant sloth. The sloths once stood around six-feet-tall and lived until about 11,000-years-ago. Researchers believe humans over-hunted them, resulting in their extinction. Now they’ve found fossilized footprints that may prove such attacks happened. They were found in the salt flats of White Sands National Monument in southern New Mexico.

Scientists say the human footprints suggest they had been walking in the exact footprints of the sloth, and confronting it.
