For the first time, scientists have uncovered fossilized footprints of ancient humans at the White Sands National Monument in New Mexico, a new study reports. And at the same site, those newly discovered human footprints were actually inside footprints of giant ground sloths — tall, fearsome creatures with sharp claws.

Scientists say this is evidence that the humans followed closely behind, or even “stalked” the sloths during the hunt.
