Hunting: Humans may have hunted glyptodonts for food and resources, contributing to their decline.
Climate change: Rapid changes in climate conditions at the end of the Pleistocene, with warmer temperatures and drying environments, created a habitat that was less favorable for glyptodonts.
Disease: Infectious diseases or other health issues could have affected glyptodon populations.
Competition: Competition with other species, such as other large herbivores, may have reduced available resources for glyptodonts.
Overall, a combination of these factors is likely responsible for the extinction of glyptodonts.
