Among the fossils of hitherto unknown mammals thatDarwin collected in South America between 1832 and 1833 during the Beagleexpedition were examples of the large, heavily armored herbivores later knownas glyptodonts. Ever since, glyptodonts have fascinated evolutionary biologistsbecause of their remarkable skeletal adaptations and seemingly isolatedphylogenetic position even within their natural group, the cingulated xenarthrans(armadillos and their allies). In possessing a carapace comprised of fusedosteoderms, the glyptodonts were clearly related to other cingulates, but theirprecise phylogenetic position as suggested by morphology remains unresolved.
