The Cingulata clade has a great taxonomic diversity, and its remains are abundantly found in the fossil record of South America, represented mainly by elements from the exoskeleton. Most of the work on cingulate fossils from the Brazilian Quaternary is restricted to taxonomy, while studies on paleobiology, including pathological aspects, are still scarce. This paper describes new exoskeletal specimens and paleopathological evidence for cingulates from Quaternary deposits in Bahia State, Brazil, among the identified taxa (Pachyarmatherium brasiliense, Tolypeutes cf. tricinctus, Propraopus sulcatus, Glyptotherium sp., Neuryurus sp., Panochthus sp., Hoplophorus cf. euphractus, Pampatherium humboldtii, and Holmesina paulacoutoi). Neuryurus is recorded for the first time in the Quaternary of Bahia. Skin lesions, possibly caused by fungi or bacteria, are identified for Panochthus sp. and Glyptotherium sp. In addition, we identified lesions caused by fleas in Glyptotherium sp. These findings underscore disharmonious interspecific relationships involving microorganisms and parasites with glyptodonts, aligning with previous research conclusions.

RESUMO – O clado Cingulata possui uma grande diversidade taxonômica e é abundantemente encontrado no registro fóssil da América do Sul, sendo representados, principalmente, por elementos do exoesqueleto. Até o presente, a maioria dos trabalhos sobre fósseis de cingulados do Quaternário brasileiro são restritos à taxonomia, enquanto estudos sobre a paleobiologia, incluindo aspectos patológicos, ainda são escassos. Este trabalho descreve novos espécimes exoesqueletais e evidências paleopatológicas para cingulados de depósitos do Quaternário na Bahia, Brasil. Os táxons identificados incluem Pachyarmatherium brasiliense, Tolypeutes cf. tricinctus, Propraopus sulcatus, Glyptotherium sp., Neuryurus sp., Panochthus sp., Hoplophorus cf. euphractus, Pampatherium humboldtii e Holmesina paulacoutoi). O registro de Neuryurus sp. é o primeiro para o gênero no Quaternário da Bahia. Lesões cutâneas, possivelmente ocasionadas por fungos ou bactérias, são reportadas para Panochthus sp. e Glyptotherium sp. Além disso, para Glyptotherium sp. identificamos lesões causadas por pulgas. Estes novos registros de relação interespecífica desarmônica de microorganismos e parasitas com gliptodontes reforçam as conclusões de trabalhos anteriores.
