“…The fossils analyzed in this work were collected from sedimentary infillings of limestone caves and natural tanks and in alluvial deposits. Most available absolute dates place the megafauna remains from tank and cave deposits from the BIR in the Late Pleistocene [ 15 , 16 ], with few exceptions assigned middle Pleistocene [ 17 ] and early Holocene ages [ 18 , 19 ]. Therefore, we considered the material studied herein as belonging to the Late Pleistocene.…”

Ectoparasitism and infections in the exoskeletons of large fossil cingulates

Studies on paleopathological alterations in fossil vertebrates, including damages caused by infections and ectoparasites, are important because they are potential sources of paleoecological information. Analyzing exoskeleton material (isolated osteoderms, carapace and caudal tube fragments) from fossil cingulates of the Brazilian Quaternary Megafauna, we identified damages that were attributed to attacks by fleas and dermic infections. The former were compatible with alterations produced by one species of flea of the genus Tunga, which generates well-delimited circular perforations with a patterned distribution along the carapace; the latter were attributable to pathogenic microorganisms, likely bacteria or fungi that removed the ornamentation of osteoderms and, in certain cases, generated craters or pittings. Certain bone alterations observed in this study represent the first record of flea attack and pitting in two species of large glyptodonts (Panochthus and Glyptotherium) and in a non-glyptodontid large cingulate (Pachyarmatherium) from the Quaternary of the Brazilian Intertropical Region. These new occurrences widen the geographic distribution of those diseases during the Cenozoic and provide more evidence for the co-evolutionary interaction between cingulates and parasites registered to date only for a small number of other extinct and extant species.

“…Além disso, táxons típicos do Lujanense argentino e uruguaio (vide Ubilla, 2004), como por exemplo, Equus (Amerhippus) neogaeus Lund, 1840, Tapirus terrestris (Linnaeus, 1758), Tayassu pecari (Link, 1795) e Ozotocerus bezoarticus (Linnaeus, 1758) também estão presentes nos tanques de João Cativo, reforçando a idade Pleistoceno Final para essa concentração fossilífera. Porém, datações numéricas realizadas em fósseis de megamamíferos de outros depósitos de tanque da RIB indicam uma idade Pleistoceno Final-Holoceno inicial (Kinoshita et al, 2005(Kinoshita et al, , 2008Silva, 2008;Oliveira et al, 2009;Dantas et al, 2011;Ribeiro et al, 2013)…”

Os depósitos de tanque, restritos ao Nordeste do Brasil, são conhecidos pelo registro de fósseis de diversas espécies de mamíferos quaternários, sendo as famílias Megatheriidae (Xenarthra, Pilosa), Gomphotheriidae (Proboscidea) e Toxodontidae (Notoungulata) as mais frequentes (Bergqvist & Almeida, 2004). Porém, embora raros, restos de anfíbios, quelônios, lacertílios, ofídios, crocodilos e aves, também
