“…As cavernas da Província Espeleológica Bambuí no município de Aurora do Tocantins (Tocantins, Norte do Brasil) são conhecidas pelo seu conteúdo fossilífero, especialmente de mamíferos atribuídos ao intervalo Neopleistoceno-Holoceno (e.g. Avilla et al, 2013;Rodriguez et al, 2013;Rodrigues et al, 2014). Estudos tafonômicos de acumulações fossilíferas de cavernas têm demonstrado uma grande variação dos processos ocorridos neste tipo de ambiente (e.g.…”

“…Estes representam os primeiros achados paleontológicos para este sítio fossilífero. Os registros encontrados neste local podem revelar importantes informações acerca da paleofauna que habitou esta região, permitindo a realização de inferências quanto à paleoecologia, o clima apresentado pela localidade durante o Neopleistoceno-Holoceno e sobre a formação da tafocenose apresentada para este depósito (Avilla et al, 2013;Rodriguez et al, 2013;Rodrigues et al, 2014;Maldonado et al, 2016).…”

, have revealed important fossil accumulations attributed to the Upper Pleistocene-Holocene. Recently, the first fossil records were recovered from the Tacho de Ouro cave, which are assigned to Tayassu pecari, Cervidae indet., Odocoileus virginianus, Mazama sp., Palaeolama major, Tapirus sp., Coendou sp. and Catonyx cuvieri. The presence of extinct taxa suggests that this fossil assemblage maybe attributed to the late Pleistocene-Holocene interval. Information on the recognized habitats for the species found in the cave indicates an environment affected by climatic variations in this interval, corroborating with the hypothesis of non-contemporaneity of the species. The presence of O. virginianus in Tacho de Ouro cave represents the southmost occurrence of the species in Brazil. The taphonomical analysis indicates that the animals probably perished externally to the cave and then were carried into the cave by a low-energy hydraulic flow, being quickly buried in contact with the vadose level of the cave. Trace fossils observed in some specimens are associated with the predation or scavenging by carnivores (Fodinichnia).

“…During the last 5 years, a great amount of mammalian fossils has been recovered from Gruta do Urso cave. Several mammalian groups were already identified in this assemblage (Avilla et al 2013;Castro et al 2013;Rodriguez et al 2013;Rodrigues et al 2014); however, the three isolated teeth presented here are the only record of tapirs. This intriguing representation of specimens can be associated to a sorting towards the more resistant specimens (teeth) face to destructive taphonomic processes, such as transport and weathering (Lyman 1994).…”

During fieldworks carried out from 2009 to 2013 in Aurora do Tocantins (northern Brazil), three isolated deciduous teeth of Tapirus were recovered. Those fossils come from a sedimentary deposit of presumed Late Pleistocene-early Holocene age in a karstic cave. This contribution aims to present a new locality of fossil Tapirus from northern Brazil, describe for the first time deciduous fossil teeth for South American Tapirus and evaluate the taphonomic aspects of those fossils. The specimens probably belong to the same individual due to there are no repeated teeth and they have the same wear pattern. Furthermore, the crowns of those teeth show no evidence of abrasion produced by transport. However, some abrasion is observed on the borders of the pulp chamber of teeth. These polishing are probably resulting of a very short transport (parautochthonous). These specimens are the only record of Tapiridae in Gruta do Urso cave; due to correspond to isolated and deciduous teeth, its identification to species level was not possible. There is not yet clear evidence that may indicate the kind of death of the individual studied here.

“…Although there is no numerical dating for the fossil cingulates described here, Electro Spin Resonance (ESR) dating of remains of a peccary (Catagonus stenocephalus) collected at Gruta dos Moura and in association with cingulate osteoderms, revealed a late Pleistocene age (20 ± 2ka; Avilla et al, 2013). In addition, a stratigraphic fossiliferous level was recognized for Gruta do Urso, and its age can be inferred based also on ESR dates of fossils from the bottom and top of this level.…”
