Glyptodons are close relatives of the little armadillo. Like armadillos, glyptodons were plant eaters. Weighed more than 2 tons. It was a protected against hunters like terror birds by its thick armor. It could not withdraw its head into its shell as a turtle does, but it could wave its club tail to scare off predators. Humans sometimes lived in the shells of dead glyptodons.
