No evidence of [[sexual dimorphism]] in ''Glyptodon'' has been described, but it has been observed in the close relative ''Glyptotherium'' based on fossils found in Pliocene deposits in Arizona''.'' In the genus, the caudal aperture of males and females differ in that the marginal osteoderms of males are much more conical and convex than those of females. Even in the carapaces of newborn ''Glyptotherium'', the marginal osteoderms are either conical or flat, which enables their sex to be determined.<ref name="Gillette-2016" /> No direct evidence of glyptodontinegroupglyptodontine group behavior has been described, though some localities preserving juveniles, subadults, and adults of ''Glyptotherium'' together are known.<ref name="Gillette-2016" /><ref name="Carlini-2022" /> Living armadillos are loners and only come together during mating season, with the number of offspring varying between one to even twelve babies depending on the species.<ref>Superina, M.
