Sebastien CLAUSEN -Associate Professor - Université de Lille


Sébastien Clausen is a French paleontologist who graduated and completed his PhD at the University of Lille where he is lecturer. His research is mainly dedicated to the evolution of ecosystems during early-mid Cambrian times with special interest in echinoderms community, associated skeletonized microfossils, and microbial consortia. He specialized in the study of disarticulated echinoderm remains, which are particularly abundant in Cambrian times and still poorly documented. His palaeobiological studies are aimed at demonstrating how important this material is for the understanding of the early echinoderm diversification. Field-geologist, he develops a multidisciplinary approach mainly based on paleontology and sedimentology.
