“…These characteristics easily differ from other Dasypodidae, in which sulci are divergent (e.g. Winge, 1915;Oliveira et al, 2014;Soibelzon et al, 2015). There are Pleistocene records of this taxon in the states of Acre, Bahia, Mato Grosso do Sul, Minas Gerais, Piauí, Rio Grande do Sul and São Paulo (Cartelle, 1999;Oliveira et al, 2014).…”

“…The number of foramina and sulcus shape of the studied material allows to distinguish it from Dasypus. Specimens of Propraopus sulcatus were also recorded in the states of Tocantins, Minas Gerais, Bahia, Piauí, Mato Grosso and Rio Grande do Sul (Castro et al, 2013;Soibelzon et al, 2015).…”

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.

“…These caves were chosen for their ease of access and because of knowledge by one of us (LSA) of their interiors from previous studies (e.g., Castro et al 2013;Rodrigues et al 2014;Soibelzon et al 2015; see these studies for a basic description of caves). These caves are separated by approximately 500 m and have no connection with each other.…”

“…The loss of these caves and their bats would be a serious setback for the conservation of the remaining Cerrado and its biodiversity. Paleontological studies have shown the importance of these caves for the fossil record (Oliveira et al 2011;Castro et al 2013;Rodrigues et al 2014;Soibelzon et al 2015).…”

Bat assemblage in a karstic area from northern Brazil: seven new occurrences for Tocantins state, including the first record of Glyphonycteris sylvestris Thomas, 1896 for the Cerrado

The Cerrado, the second largest morphoclimatic area of South America, has many limestone outcrops with caves. However, studies of the bat fauna in karstic environments in the Cerrado are scarce. We present an inventory of bats in a karstic Cerrado area in the Tocantins state. We used mist-nets to sample caves, savannas, deciduous forests, and periurban environments. We captured 516 bats of 30 species, revealing that the study area is one of richest for bat species in the Brazilian Cerrado. Seven new occurrences of bat species were recorded for the Tocantins state, and we report the first record of G. sylvestris from the Cerrado biome. We recorded 21 species simultaneously at one cave, Gruta dos Moura, which is the highest species richness of bats for a single cave in the Neotropics.

Pubenza is a remarkable palaeontological site of Colombia, and a place that could hold some of the potentially oldest evidence of humans in northern South America. Previous palaeontological research at this site has mainly focused on the megafauna. Here we describe and establish the systematic palaeontology for the small fauna that inhabited this ancient lacustrine ecosystem, including the first report of birds, tortoises and vipers for the Late Pleistocene in Colombia. Furthermore, exceptionally well preserved fossilised wasp nests are morphologically and elementally characterised, which is the first report of an ichnofossil of this kind in northern South America. In addition, new material of kinosternid turtles, armadillos and rodents is also described. Our results reveal that the Bogotá River Basin, where Pubenza is located, was a rich ecosystem during the Late Pleistocene and a region of great interest for future articulated palaeontological and archaeological studies.
