Glyptodonts were large, armadillo like mammals that lived between twenty and three million years ago. Originally they had armadillo-like armor, but evolved to have armor fused like a dome with a “helmet” for its head and even armor on its tail! This armor was made of skutes, or scales. Glyptodonts were grazing animals, with powerful teeth and jaws for grinding vegetation.
