New Mexico: fossilized tracks point to ice age hunters who tracked giant sloth

Tracks in White Sands national monument suggest hunters tracked 8ft creature with long arms and sharp claws - but it's unclear why

Researchers studying a trail of fossilized footprints on a remote New Mexico salt flat have determined that the tracks tell the story of a group of ice age hunters stalking a giant sloth.

Scientist David Bustos said the tracks, both adult and children's footprints found at White Sands National Monument, showed people followed a giant ground sloth, purposely stepping in their tracks as they did so.
