“…12). The results here contrast with other similar studies, such as Santos et al (2002), Vasconcelos et al (2015), Maldonado et al (2016) and Buchmann et al (2017), who verified a higher proportion of transported fossils in deposits formed from gravity and water flows. Most fossils recorded in the present study are linked to different endogenous sedimentary deposits, with a few of them preserved in encrustation beds, which shows a time averaging.…”

“…On the other hand, such exposure was exactly what allowed the sampling of a significant amount of material in almost all sectors of these caves in a relatively short period of time, what would be impossible through controlled excavations (e.g. Vasconcelos et al, 2015). Thus, it was avoided the impacts of cave excavation which could compromise other studies in these environments, such as those involving the current biota (e.g.…”

The study of two caves from the Serra do Ramalho region is here presented, this is one of the most important karstic areas in Brazil. A taxonomic analysis revealed 29 taxa including Xenarthra, Cetartiodactyla and Carnivora, ranging from Late Pleistocene to Early Holocene. Taphonomic studies reveal taphocoenosis consisting mainly of complete elements, without significant transportation, but also of transported elements, composing spatial-mixed, predominantly in situ-preserved assemblages. The predominance of Xenarthrans found within the caves is probably biased by a taphonomic pattern since these animals would have life habits related to cave environments, therefore with higher chances of preservation. There is evidence of accidental death of the scelidotheriines in Lapa dos Peixes cave, where entrapment of the animals during one or more events of river flooding is pointed as a hypothesis. Deposition took place within different periods of dry and humid climate incorporating bones in clastic and chemical deposits. Cycles of sedimentary deposition and reworking (erosion) may have acted in generating complex and overlapping depositional patterns with time averaging. During depositional phase, while the cave environment was occupied rather by Xenarthrans, parts of other animals were transported in the scope of fluvial systems and gravity loads, as well as by accidental falling or scavengers. The sedimentary deposits are currently being eroded by rain runoff in both caves, causing the reallocation of finer sediments to deeper conduits but the fossils keep close to their original location. This process is exposing a large amount of fossils, allowing extensive sampling which would be impossible with active excavations, since it would require an excessively longer time and damages to the caves.

“…A primeira citação foi feita por Lund (1843), a partir de um fragmento de maxila descoberto na Lapa da Escrivânia em que Paula Couto (1979) reconheceu a espécie, mas considerou duvidosa a presença no Pleistoceno. A outra ocorrência no estado de Minas Gerais foi feita por Vasconcelos et al (2015) que identificou um fragmento mandibular, mas considerou o espécime como pertencente ao Quaternário e não foi atribuída uma idade específica, podendo ser um espécime recente.…”

presença de Irara (Eira barbara) em sítios arqueológicos, etnográficos e paleontológicos no Brasil

Os mustelídeos possuem ampla distribuição geográfica e habitats variados. O território brasileiro possui cinco espécies desta família, observados em sítios paleontológicos, arqueológicos e etnográficos. A irara, Eira barbara, é um mustelídeo de florestas, onívoro e que necessita de grande área geográfica para viver. O presente trabalho aborda as ocorrências em sítios paleontológicos, arqueológicos e no sítio etnográfico Guajá, além de comentar características osteológicas. Por ser um animal de hábitos preferencialmente arbóreos a presença em sítios paleontológicos como cavernas, é raro. Os estudos no sítio etnográfico Guajá demonstraram que o consumo ocorre em comunidades indígenas, mas em sítios arqueológicos as ocorrências são muito poucas e restritas a partes ósseas indeterminadas, podendo ter origem natural ou antrópica.

“…However, despite this huge number of recorded cavities, fossils have been recovered from only a few of them (see Cartelle, 2012). Likewise, taphonomic analyses of fossils recovered from several Brazilian caves are scarce (e.g., Auler et al, 2006;Gasparini et al, 2015;Vasconcelos et al, 2015Vasconcelos et al, , 2018Maldonado et al, 2016;Araújo-Júnior et al, 2017a;Buchmann et al, 2017;Silva et al, 2019a), especially in comparison to tank deposits (see Araújo-Júnior et al, 2017b), another common type of deposit of the BIR.…”

Mammal Taphonomy in a Cave Deposit From Quaternary of Brazil

et al. 2022

In Brazil, the Quaternary caves of the Brazilian Intertropical Region (BIR) host important fossiliferous deposits of terrestrial vertebrates, whose fossil content is taxonomically well known. Here, we conducted a taphonomic analysis based on macroscopic and microscopic features of 543 specimens collected in the F3 cave, a fossiliferous deposit located in the municipality of Baraúna, northeast of Brazil. This deposit encompasses 17 taxa, but it is dominated by fossils of Eremotherium laurillardi. Most bones were buried in less than a year, but the taphonomic history of this deposit was governed by alternation of dry and wet cycles. This led us to recognize four taphonomic modes, that differ according to the climatic conditions in which the bones were preserved as well as the time interval between the accumulation and the final burial of the remains.
