Where did the glyptodon live?

Apatosaurus survived by eating leaves and drinking water. If they were similar to modern browsers, they may have spent as much as 20 hours per day. They would have traveled in herds, constantly moving in search of food. The herd, along with their huge size, would have been the main defense against predators for adults. They reproduced by laying lots of eggs, which they probably left to fend for themselves.
