Article
Many species experienced population turnover and local extinction during the Late Pleistocene. In the case of megafauna, it remains challenging to disentangle climate change and the activities of Palaeolithic hunter‐gatherers as the main cause. In contrast, the impact of humans on rodent populations is likely to be negligible. This study investigat...
Article
Quaternary faunal remains are key for the understanding of the effect of climatic changes on both animal and human populations. Here we show for the first time in Atapuerca the analysis of an avian assemblage through the MIS9/8 boundary, a moment of climatic deterioration that coincides with the spread of Neanderthals and the adoption of Levallois...
Article
The Ebro Basin (Spain) is one of the few worldwide areas where Palaeogene avian and mammal tracksites have been found. A new unpublished tracksite known as La Sagarreta is here described. The tracksite is located in a sandstone-dominated outcrop from the Early Oligocene Peralta Formation in the northern-central sector of the basin. Six different ic...
Article
The Lateglacial to Holocene transition is a key moment for understanding the extant configuration of bat populations in Western Europe, where several species are currently under threat. The Chiroptera fossil record for this period and region is poorly known. Here, we present the bat fossil record along the stratigraphical sequence of El Mirador (Bu...

Article
Full-text available
Small vertebrates are a key proxy for paleoenvironmental and paleoclimatic reconstruction, but a previous taphonomic analysis of the paleontological assemblage is needed before facing this kind of approach. Works concerning taphonomy of preyed small vertebrates are abundant in the literature, but chiropters are not usually included as they are only...

As the south-westernmost region of Europe, the Iberian Peninsula stands as a key area for understanding the process of modern human dispersal into Eurasia. However, the precise timing, ecological setting and cultural context of this process remains controversial concerning its spatiotemporal distribution within the different regions of the peninsul...
Article
Palaeoenvironmental reconstruction of early Pleistocene sites has a particular interest as it sheds light on how the arriving of the first Europeans occurred, as well as on the nature of the relation between these humans and the ecosystems. Bird remains are useful tools for this purpose, because they are commonly represented in the assemblages and...
Article
In contrast with the well documented strain on extant amphibian and reptile populations today, the Quaternary fossil record of these groups is very conservative showing few changes over long periods of time. In order to establish the non-human-induced effect of climate change on herpetofaunal diversity, we collected data from Pleistocene sites in t...

The Chalcolithic levels of El Portalón de Cueva Mayor (Atapuerca, Burgos, Spain) offer a good opportunity to test whether the small-mammal contents of different archaeo-stratigraphical units may be useful to characterize them as independent entities. With that purpose, we studied representative samples of small-mammal remains from the two main cont...
Article
Fish bones are common in Pleistocene cave deposits in Europe. In this paper, we report on fish remains from the Gran Dolina cave (Trinchera del Ferrocarril) in the Sierra de Atapuerca in Spain, to increase what is known of the freshwater ecosystems close to the cave. The 19-m-thick section, divided into 11 stratigraphic levels, represents an Early...

Here we analyze the fossil remains of Castor fiber from the Middle Pleistocene site of Gruta da Aroeira, in the Almonda karst system, Tagus basin (Torres Novas, Portugal) and discuss the archaeological implications of the presence of beavers in the region. The Almonda karst system has been the backdrop for human evolution in Portugal, because there...
Article
The interior of the Iberian Peninsula has orographic conditions that make this territory especially vulnerable to Quaternary climate oscillations and which actually could have made it decisive for Paleolithic human populations at critical points. For this reason, the information provided by paleon-tological sites is important for reconstructing cli...
Article
Rodents are a very useful tool in reconstructing the environment of the past, especially owing to their rapid response to climate change, their small home range, and their restricted habitat requirements. They are a highly diverse group of mammals, which have high reproduction rates and as a result can evolve rapidly. The abundance of their microfo...

Full-text available
The harsh climatic conditions during the Last Glacial Maximum (LGM) period have been considered the cause of local extinctions and major faunal reorganizations that took place at the end of the Pleistocene. Recent studies have shown, however, that in addition many of these ecological events were associated with abrupt climate changes during the so-...

Article
Mimomys savini is a very important arvicoline as it represents a useful biochronological tool in the study of the first human arrivals in Europe and its expansion across the continent. To date, evolution studies on this species have focused on its size changes and the loss of ancestral characteristics. This work sheds further light on the evolution...
Article
Fossil bats are common components of Pleistocene palaeontological cave-sites, sometimes appearing in levels with evidence of a human presence. As with other small vertebrates, variations observed in fossil bat palaeocommunities through a stratigraphic sequence may be correlated to palaeoclimatic and palaeoenvironmental fluctuations. As many bat spe...

The Myotis myotis/M. blythii species complex, spread across the Western Palearctic, is a problematic group for which the taxonomy of the species is not yet satisfactorily resolved. The Iberian Peninsula played a key role in its evolutionary history as a Pleistocene refuge and as the starting point for the eastward expansion of M. myotis in the earl...
Article
Bat remains occur in low numbers in Pleistocene cave assemblages compared to other small vertebrates, and therefore are rarely used as palaeoenvironmental or palaeoclimatic indicators. In this study we address the correlation between bat palaeocommunity dynamics and climate and environmental factors by analysing the fossil bat record throughout the...
