The Quaternary vertebrate paleontology of the Brazilian Intertropical Region is well-known, but there are only a few publications on bone ichnology. In this paper, we analyzed trace fossils in 23 bones Gruna das Três Cobras, Complexo Suíço, and F3 caves, which located Bahia Rio Grande do Norte states, Region. We discovered gnaw marks assigned to Machichnus bite attributed Nihilichnus, as well insect modifications referring single (Cuniculichnus, Gunnellichnus, Karethraichnus, Osteocallis)...
Fósseis de mamíferos quaternários são conhecidos para vários depósitos fossilíferos do Estado Rio Grande Norte. No entanto, grande parte conhecimento sobre essa mastofauna é taxonômico, enquanto que aspectos estratigráficos, tafonômicos e paleoecológicos têm sido pouco discutidos. Este trabalho uma síntese as ocorrências fósseis no Quaternário É fornecida listagem completa atualizada dos táxons das localidades fossilíferas discutidos relacionados à tafonomia, diversidade, posicionamento...
In this work, the first occurrence of carnivore/scavenger teeth marks on Pleistocene fossil mammals collected in Northeastern Brazil is reported.The fossils are from "Tank Jirau", Itapipoca municipality, Ceará State, and housed Museu de Pré-história Itapipoca.The observed features, which assigned to a largesized canid, correspond scratches mostly perpendicular long axis bone, occurring mainly ribs, vertebrae, tibiae ulnae.Based size scratches, geographical distribution dietary habits canids...
FTI) IN BONE REPRESENTATIVITY ANALYSES.In this work FTI is applied in order to obtain more refined conclusions about the transport process involved taphonomic history of these accumulations.Data bone representation from Fazenda Nova tank (in Brejo da Madre de Deus Municipality, Pernambuco State), Jirau and João Cativo tanks (both Itapipoca Ceará State) fluvial deposits Araras/Taquara (outcrops Rio Madeira Formation, Rondonia were used analysis.Using Spearman's nonparametric correlation...
This work reports the occurrence of fossil remains anurans attributed to taxa Rhinella jimi, R. schneideri e Anura indet., from tank deposits Joao Cativo Paleontological Site (Late Pleistocene-early Holocene), municipality Itapipoca, Ceara State. is fi rst formal description bufonids in Brazilian fossiliferous deposits. The presence jimi and at site suggests an arid paleoenvironment with marked seasonality. During raining periods, tanks probably were foraging, breeding dying sites for...
We performed a macroscopic and radiological inspection in set of bones belonging to the fossil mammal assemblage Zabelê Paleontological Site (Late Pleistocene-Northgrippian), northeastern Brazil. Radiological analyzes were carried out using conventional X-ray microtomography (µCT) equipment. This study revealed four different types diseases (calcium pyrophosphate deposition disease – CPPD, infection, trauma tendon avulsion) restricted giant ground sloth E. laurillardi (5.36% MNI) an...
