Dr. Michael Newbrey is interested in the biology, systematics, phylogeny, and ecology of fishes with particular interests in the effects of climate change on the evolution of age and growth of fishes. His research integrates the disciplines of paleontology, ichthyology, fisheries, ecology, and geology to explore questions regarding the evolutionary changes in marine and freshwater fishes. Michael’s fieldwork and published research has focused on sharks, rays, and boney fishes from the Mesozoic and Cenozoic deposits of North America, Great Britain, Poland, Mongolia, and Australia.
Education and professional affiliations
Michael’s degrees include a bachelor’s degree in biology and a master’s degree in natural resources/fisheries from the University of Wisconsin at Stevens Point. He obtained a Ph.D. in Zoology from North Dakota State University studying the age and growth of extant and extinct fishes to examine the influence of climate change on the evolution of freshwater fish biology and ecology. Subsequently, Michael spent six years as a post-doctoral fellow at the Royal Tyrrell Museum of Palaeontology (Betsey Nichols Post-doctoral Fellow) and the University of Alberta where he published on sharks, rays, and boney fishes with colleagues from around the world. His research continues at Columbus State University, Columbus, Georgia, USA, where he is currently teaching, and here at the Canadian Fossil Discovery Centre as an Adjunct Curator of Fossil Fishes.
Currently, Michael is working on describing sharks and rays from an Albian deposit in Poland with colleagues at the Polish Academy of Sciences and the Western Australian Museum. Ultimately, he wants to compare sharks and rays from Poland and Australia to those of the same age deposits in Manitoba. Michael exclaims “Manitoba boasts marine deposits of a variety of ages in the Cretaceous that are virtually unexplored for palaeontological resources. Palaeontologists have been working in Manitoba for a long time, but they have barely scratched the surface to explore 35+ million years of rich, marine, palaeontological resources from a unique marine habitat. Consequently, a plethora of questions can be posed using fish fossils (and other aquatic organisms) from Manitoba. Around 100 mya, SW Manitoba was covered by an interior sea that extended from Utah and Kansas, north to the Arctic, the Cretaceous Boreal Ocean. At that time the Artic was ice free and Artic fishes colonized the interior sea of North America. Michael is curious how the fishes living in Manitoba compare to southern, high latitude marine fishes of Australia, and the mid-latitude marine fishes of Cretaceous Poland. Studying these ancient fishes from Manitoba will provide many insights into their geographic distribution, biology, evolution, and ecology. Furthermore, I think Manitobians will enjoy the stories that their rich fossil heritage has to tell about Manitoba’s deep faunal history.”
