Research Summary

My research focuses on micropalaeontology of late Mesozoic (Late Jurassic - Early Cretaceous) non-marine deposits. Central aspects of my research are the taxonomy, phylogeny, palaeobiology and biostratigraphical application of ostracods (microcrustaceans of around 1mm size with a calcified bivalved shell, the carapace), that today inhabit virtually all aquatic environments, both marine and non-marine). Ostracods' small size, morphological variability, ecology, fossilization potential and long geological history render them excellent candidates for a wide array of applications. In non-marine deposits, ostracods are among the most common fossils, at least since the Middle-Late Jurassic, and consequently one of the most useful groups.
