Introduction
My research interests are focused on the investigation of past environmental and climate variability by means of biogeochemical analyses on geological and paleontological archives. I specialized on stable isotope biogeochemistry of Mesozoic and Cenozoic vertebrates, invertebrates and organic matter enclosed in the sediment, although I have used a range of biogeochemical proxies such as trace elements, rare earth elements and biomarkers. I have mainly worked on the Iberian and South American geological and paleontological record, where we are exploring global/regional/local paleoclimatic, paleoenvironmental and paleoecological shifts.

Whether diversity is bounded or not is a hot topic in macroecology and macroevolution. But deep-time studies of diversity dynamics and its potential regulators are usually conducted at the clade level or at the continental or global level. We are using the well-known Iberian paleontological record to investigate how changes in species ecological function and physical environment shaped mammals diversity 16 - 2 Ma in this region.

Abstract The reconstruction of deep-time diversity trends is key to understanding current and future species richness. Studies that statistically evaluate potential factors affecting paleodiversity have focused on continental and global, clade-wide datasets, and thus we ignore how community species richness build-up to generate large-scale patterns...

Proboscideans are so-called ecosystem engineers and are considered key players in hypotheses about Late Pleistocene megafaunal extinctions. However, knowledge about the autoecology and chronology of the proboscideans in South America is still open to debate and raises controversial views. Here, we used a range of multiproxy approaches and new radio...

Conference Paper
Full-text available
The roles of environmental and biotic factors in shaping diversity has been mainly assessed at large evolutionary and taxonomic scales, generally looking at entire clades and continental species pools. We investigate the influence of competition, functional diversity, local and global environmental changes, as well as biogeographic events on the di...
Article
The northern coastal area of the Iberian Peninsula shows an excellent archaeo-paleontological record with a unique representation of Pleistocene mammalian fossils. While the Late Pleistocene is better recorded, the Middle Pleistocene record remains more fragmentary. The Punta Lucero site (Biscay) has yielded the most important fossil assemblage of...

Carnivore-rich fossil sites are uncommon in the fossil record and, accordingly, provide valuable opportunities to study predators from vantages that are rarely applied to ancient faunas. Through stable isotopes of carbon and a Bayesian mixing model, we analyze time-successive (nearly contemporaneous), late Miocene carnivoran populations from two fo...

We determined the lipid distributions (n-alkanes, n-alkan-2-ones, n-alkanoic acids), total organic carbon (TOC), total nitrogen (TN), Ca/Mg and ash content in Las Conchas mire, a 3.2 m deep bryophyte-dominated mire in Northern Spain covering 8,000 cal yr BP. Bog conditions developed in the bottom 20 cm of the profile, and good preservation of organ...

The lipid content of three cores from Lake Enol (Picos de Europa National Park, Asturias, Northern Spain) was studied. The n-alkane profiles indicated a major input from terrigenous plants [predominance of high molecular weight (HMW) alkanes) since ca. 1695 AD to the water body, although the uppermost cm revealed a predominance of organic matter (O...

The modern South American mammalian assemblage was determined by the closure of the Panama isthmus (similar to 2.7-3.1 Ma) and later on, by profound climatic and environmental fluctuations occurred during the Quaternary as well as by the appearance of humans in the continent. In the present study, stable isotope analyses (delta C-13, delta O-18(CO3...
Article
Trace element analysis of fossil bone and enamel constitutes a useful tool to characterize the paleoecological behavior of mammals. Up to now, most trace element studies have focused on Plio-Pleistocene fossils. Here, we show that paleodietary inferences based on trace element analyses can be also obtained from ~14Ma old Miocene mammals, in a perio...
