Both present-day and fossil molluscan assemblages offer an opportunity for a better understanding of the structure and organization of both modern and past benthic communities. In this framework, drill holes are used widely to explore predator–prey interactions. This research focuses on predation marks, especially drill holes, recorded on modern mo...
Drilling predation plays an important role in the evolution and diversification of organisms, and is one of the most studied biotic interactions in fossil and modern records. Marks of drilling predation on mollusc shells are proof of food activity and the selective pressure of one taxon on another. In this study, we explore drilling predation on pr...
As a biotic interaction, drilling predation is affected by the evolutionary histories of the predator and prey, as well as the environment. A unique location with distinctive evolutionary histories and environmental conditions is the remote island of Rapa Nui. For mollusks, an evolutionary history in relative isolation has led to high rates of ende...
One of the most abundant species of bivalves found on modern beaches and Quaternary deposits in the San Matías Gulf (Argentinian Patagonia, SW Atlantic Ocean) is Glycymeris longior. Its high abundance and broad geographical distribution turn G. longior into a target species for taphonomical studies. Here, we described the taphonomic signature regis...
A tephra layer was recovered within the Holocene fluvial succession of
the Cerro Colorado Cultural and Natural Reserve in the Córdoba Province
(Argentina). Radiocarbon dating on organic matter preserved within the
paleosoil beneath the tephra layer indicate that the ash layer is younger

a developing ecosystem and presents extraordinary and distinctive coastal morphological features that preserve the paleoenvironmental history of the region. This study aims to develop a landform inventory and to characteri...
We report the results of bioarchaeological, genetic, malacological, and lithic analyses of a burial located in the Calamuchita Valley in the province of Córdoba in central Argentina. We discuss these findings from an osteobiographical perspective that considers the physical body from three spheres of analysis: biological, social, and political. The...
Since the impacts of climate change on marine benthic organisms are already detectable in many aspects, it is crucial to address the potential responses of marine organisms and their interactions with the environment. In particular, the study of phenotype traits along latitudinal gradients is a powerful tool for exploring species responses in a cha...
The analysis of predation traces on shelled taxa is a primary source of data for studying predator–prey interactions in both
modern and past ecosystems, and provides valuable information along ecological and evolutionary timescales. For Antarctica,
there is little information about predation traces on shelled taxa, and the available studies come al...

The Andean Condor (Vultur gryphus) is a culturally iconic wildlife symbol for the South American Andes, but is naturally found at very low population densities, and is increasingly threatened. Using the Range Wide Priority Setting methodology, we (a group of 38 Andean Condor experts) updated the Andean Condor historical range (3,230,061 km2), syste...
In the central region of Argentina, there is a diverse land snail fauna dominated by endemic species. Among them, Austroborus cordillerae (Doering) is a little-known species that could be on the verge of extinction. This work therefore provides updated information on the records of shells by incorporating new field findings.
It is important to understand the historical precedents of current situations to be able to anticipate where the current global environmental and climatic change may lead. Geo-historical data provide information beyond the limitations of instrumental data. This study aims to reconstruct components of the palaeoclimatic and palaeoenvironmental histo...

An axe head and a round bead were found at the burial site of an adult male (dated at 3770 ± 90 14C years BP) at Amboy, Córdoba (central Argentina). These artifacts were studied using electron microprobe, scanning electron microscopy and X-ray diffraction, for a complete characterization of the materials and to infer the source. The axe head is car...
Knickpoints are an expression of disequilibrium in a fluvial system and they occur in both alluvial and bedrock rivers. A significant amount of research in the past decade around the globe demonstrated the usefulness of the knickpoints as geomorphic markers, specially in active margins, which due to its formation is related to tectonic, climatic an...
Environmental change, such as variation in upwelling and the consequent fluctuation in marine primary productivity, may have profound effects on organisms. Trophon geversianus shells from Caleta de Los Loros (San Matías Gulf, Northern Patagonia, Argentina) were analyzed in order to compare morphological variability at different spatio-temporal scal...
An analysis of a set of malacological fragments, belonging to the giant snail Megalobulimus lorentzianus (Doering 1876) or Borus from an excavation carried out in Cerro Colorado (province of Córdoba), is made. The results obtained suggest that the stratigraphic deposits from which these fragments were recovered would be of anthropic origin, since t...
El atractivo por las Ciencias de la Tierra en la sociedad se mantiene presente, aunque la información disponible es, en general, muy técnica o enfocada a otras regiones del planeta. Cicterránea surge para compartir los conocimientos generados en el Centro de Investigaciones en Ciencias de la Tierra (CICTERRA, CONICET, FCEFyN-UNC). Su objetivo es ap...
Although environmental variability generates differences in the preservation of shell assemblages, intrinsic variations in shell characteristics can confound the effects of environment on preservation. However, several studies proposed that the composition of shell supply only affects the intensity of alteration but not its preservation trend along...

Although different studies in Antarctica have dealt with benthic communities, few studies have focused on molluscan assemblages and their ecology. During the austral summer of 2011, 17 stations between depths of 68.5 and 754 m were sampled in West Antarctica using a demersal bottom trawl pilot net on board RV ARA Puerto Deseado. In all, 1848 specim...
The aim of this study is to describe and interpret the paleoenvironmental history of the San Matiás Gulf (SMG), in northern Patagonia, Argentina, which is associated with possible biotic and abiotic changes that occurred during the late Quaternary. In this regard, a taphonomic (disarticulation, right/left valve ratio, fragmentation, abrasion, teeth...
There is growing concern about the impact of contemporaneous ocean acidification on marine ecosystems, but strong evidence for predicting the consequences is still scant. We have used the gastropod Trophon geversianus as a study model for exploring the importance of oceanographic variables (sea surface temperature, chlorophyll a , oxygen, calcite a...
The modern Antarctic bivalve fauna has long been considered as unusually small-sized or 'dwarf'. However the validity of this pattern and the underlying causes remain little studied. We used a worldwide compilation of body sizes of 5185 bivalve species across 17 major biogeographic provinces to show that Antarctic species are statistically smaller...
The use of rocky intertidal assemblages in paleoecology and conservation paleobiology studies is limited because these environments have low preservation potential. Here, we evaluate the fidelity between living intertidal mussel bed communities (life assemblages or LAs) and mollusk shell accumulations (death assemblages or DAs) from the environment...
The Glacidorbidae, a family restricted to the Gondwanan realm (Tasmania, southeastern and southwestern Australia, and southern Argentina and Chile), previously included five genera with 20 identified species; 19 of them are Australian, with one genus and species, Gondwanorbis magallanicus (Meier-Brook & Smith, 1976), from South America. Here we des...
Amiantis purpurata shells from the San Matı´as Gulf (SMG) were analysed in order to compare both morphology and size throughout the late Quaternary in relation to environmental changes. Shells from modern beaches, Holocene marine assemblages (late Holocene, 3630 +100 years BP) and interglacial Pleistocene marine assemblages (MIS 5, 100 ka years BP)...
The most recent Quaternary marine transgressions are well represented along the South Atlantic coast. In the Colorado River delta (39°15′S-39°55′S), south of Buenos Aires Province these deposits are mostly littoral ridges and tidal plains with abundant fossil marine fauna. Seventeen localities were analyzed (five Pleistocene, seven Holocene and fiv...
Little is known about the effects of Holocene climate variability on marine environments and their biota in southern South America. Fossil shells of the aragonitic bivalve Retrotapes exalbidus (Dillwyn) offer the possibility of investigating climate variability and particularly the seasonal dynamics of sea-water temperature in the Beagle Channel du...
