Biography

Research

Professor Paul Wignall lectures in palaeontology and sedimentology. His principal research goal is to understand the origins of mass extinction events. He has been investigating the end-Permian mass extinction since the late 1980s and in recent years has broadened his research topics to include the late Devonian (Frasnian/Famennian), end-Triassic and Early Jurassic (Toarcian) mass extinction events. His multidisciplinary approach to the origins of these crises in Earth's history includes the study of their fossil, sequence stratigraphic and their stable isotope records. Evidence for marine anoxia is often associated with all of these extinction events and this nicely overlaps with Professor Wignall's other main research interest: the characterisation of black shale depositional environments. As many of the key extinction boundary sections are not found in West Yorkshire, Professor Wignall has been forced to travel to often remote parts of the globe: his favourite field areas to date have been Nevada and central Poland. He has published over 130 research articles and 2 books.
