Their Shells
Glyptodons were hunted for a lot of reasons by humans. First off, their shell is pretty huge, and as such, humans wanted them as a form of shelter. It is also believed by many that people who lived in those days lived in caves. So, there might not have been a lot of caves in existence, and seeing the shells could hold around 2 to 3 people, it was quite useful. Interestingly, there were also other reasons why they hunted them.
