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.
New paper on a 3D, full-body reconstruction of the Megalodon
Our new paper has been published in Science Advances. Based on an exceptionally preserved specimen, we reconstructed the entire body shape of the extinct giant shark, the Megalodon. Our model further allowed us to infer movement and feeding ecology, revealing unprecedented swimming & prey intake abilities.
