We study marine diversity through time.
Our research aims to better understand the extinction mechanisms of marine life, especially sharks, and to assess the impacts of species loss on functional diversity. Our ultimate goal is to use this information to provide insights into conservation. To reach our research objectives, we integrate large sets of paleontological and neontological data and apply methods in ecology, evolution, phylogenetics and biogeography.

A perspective on new research
An exciting, new study by Sibert and Rubin in Science based on deep sea core sediments suggests that today's low diversity of oceanic sharks might be the result of a dramatic and mysterious extinction event, ~19Ma.
Pimiento and Pyenson wrote a perspective on this finding, pointing out that such dramatic biodiversity loss feels like a déjà vu given that today, overfishing is causing an extinction of similar proportions (but at at a much faster rate) not only in the the open ocean, but also in shallow waters.
