Research is mainly focused on the study of marine and terrestrial palaeoecosystems during the Mesozoic and Cenozoic periods in an attempt to reconstruct palaeoenvironments. The following aspects are covered:
Relationships and interactions between palaeoecosystem evolution and global climate change, including abiotic and/or biotic factors (organic matter production: CO2 capture by photosynthesis, secondary production and carbonates) at global, regional and local scales.
Palaeobiodiversity is reconstructed by diverse approaches (comparisons with current biodiversity, reference databases, morphometric and statistical methods) coupled with environmental parameters (temperature, humidity, salinity, seasonality) with the contribution of direct isotopic analyses and/or contextual information. Data on continental palaeoclimates (palaeo-vegetation) can be compared with those obtained from the marine environment.
Environmental changes are not necessarily synchronous in the regions observed which results in adaptation of some taxa earlier in some areas than in others. This has been followed by their dispersal to later affected geographical areas. Extinctions or survivors are examined in the light of regional or local pecularities (endemism, isolation, refuge areas).
