>> It was a battle for the ages. Prehistoric big game hunters confronting a giant ground sloth towering over them. That's being retold today from the footprints man and beast left behind in New Mexico. And no, giant sloths would not have been as easy as hunting their modern and hilariously slow tree dwelling cousins.

>> It's a big big animal, so seven and a half, eight feet tall, fairly long arms with very very long sharp claws that are used to gripping, reaping trees. Same with it being a formidable prey.>> Scientists who made the discovery say it probably went down like this.
00:00:44
Humans stalked their prey by following in its footprints. This print has both a sloth's impression and a human's inside. There were also human tracks further away. The team thinks this means that the hunters worked as a group. With one bunch trying to distract the animal as another tried to land the killing blow.

This circular print is thought to show how the sloth would have reared up on its hind legs, flailing.>> Getting two sets of fossil footprints that interact, that show you the behavioral ecology is very, very rare.>> Most scientists believe ancient man drove giant sloths to extinction 11,000 years ago.

Although, it's not clear who won this particular battle. They didn't find any bones and couldn't follow the tracks to their end due to budgetary constraints. 3D technology used the model of footprint was specially designed by the team. But it since been adopted for law enforcement use. They said it uses machine to running to match patterns in shoe prints that already helped solve the case in United Kingdom
