Late Ordovician Brachiopods from West-Central Alaska: Systematics, Ecology and Palaeobiogeography

About Christian M. O. RasmussenDavid A. T. HarperRobert B. Blodgett

Christian M. Ø. Rasmussen is a postdoctoral researcher at the Natural History Museum of Denmark. His main research focus on what governs fluctuations in biodiversity through time. He has particularly specialised in Middle Ordovician through Lower Silurian brachiopod faunas and notably their response to the Great Ordovician Biodiversification Event as well as the End Ordovician mass extinctions. Recently however his research has focused on causes to Neogene biodiversity fluctuations with a special interest in the development of biodiversity hotspots. David Harper is a leading expert on fossil brachiopods and numerical methods in palaeontology. He is Professor of Palaeontology in Durham University Principal of Van Mildert College and Deputy Head of College Faculty (Research). He was previously Head of Geology in the Natural History Museum of Denmark. He has published over 10 books and monographs including a couple of influential textbooks as well as over 250 scientific articles and together with Øyvind Hammer the widely-used software package PAST. Robert B. Blodgett is a geologist/paleontologist whose research is focused on Paleozoic and Mesozoic faunas of western North America especially Alaska. His primary specializations are with gastropods and brachiopods but his work in the Mesozoic also includes bivalves and foraminifera. He was formerly with the Branch of Paleontology & Stratigraphy of the U.S. Geological Survey until the untimely demise of that unit in 1995 and he now works as independent consultant.
