South America has a diverse and rich fauna of fossil mammals, with species that would seem rare and extraordinary to us today. Among these species, glyptodonts stand out for their amazing anatomy and evolution. Their unique characteristics, abundance, and remarkable diversity make them ideal for popularizing paleontology. However, the general public has little knowledge about glyptodonts. The current generation of palaeontologists is conducting an in-depth review of the systematic, phylogenetic, and biogeographic history of glyptodonts to provide a clearer view of their biology, evolution, and the ecosystem in which they lived.
