David Harper

David Harper is a Visiting Research Fellow in the Department of Geology at Lund University, specializing in paleontology and stratigraphy with emphasis on Ordovician period geology and brachiopod evolution. His international collaborations span Sweden, South Africa, Ireland, and Greenland.

Harper's research focuses on mass extinction events, bioregionalism, and fossil assemblages in deep-water environments. He investigates paleoenvironmental reconstruction through brachiopod-dominated shell concentrations and Ordovician stratigraphy, contributing to understanding biogeographic patterns and ancient climate impacts. Key areas include Greenland geology and Malvinoxhosan bioregion dynamics.

Recent publications (2021-2024) reveal concentrated work on Ordovician-Cambrian transitions across multiple continents. His studies integrate sedimentology and paleontology to analyze biocrises, fossil preservation, and taphonomic processes, with notable outputs on South African geology and Carboniferous cnidarian morphology.

Harper maintains active international collaborations, as evidenced by co-authored works with researchers across Sweden, South Africa, Ireland, and Greenland, reflecting a globally networked research approach in Earth sciences.
