摘要

Alterations in the exoskeleton of glyptodonts that were produced during their lifetime can provide valuable insights into their behavior. By examining the exoskeletons of well-known glyptodont genera through techniques such as macroscopic inspection, radiography and digital microscopy, we have identified alterations including fractures, deformations, and perforations, some of which are linked to infections. This study presents the first documented instances of trauma-induced alterations in the exoskeleton of Panochthus, Hoplophorus euphractus and Propalaehoplophorus australis, along with additional cases for Glyptodon. We reinforce the role of the tail club in intraspecific combat among glyptodonts, drawing parallels to the presumed behavior of ankylosaurs based on comparative anatomy and the nature and distribution of exoskeletal lesions. We also discuss how sexual selection may have influenced glyptodont morphology.
