Scott Persons

’11 MSc, ’16 PhD, PDF

Scott’s research focused on the tail anatomy of non-avian theropod dinosaurs, which includes the big carnivores like Tyrannosaurus and Albertosaurus. He performed dissections on modern animals to examine relationships between tail bone structure (which would be preserved in the fossil record) and tail musculature and flexibility. Some dinosaur tail muscles were connected to their leg bones, as well as to their hips, so his work has direct implications for assessments of dinosaur speed. Scott was also concerned with charting evolutionary trends and specializations in tail morphology across the theropod lineage. Beyond research, he was involved in the design and curation of several exhibits at the University of Alberta and various institutions in the United States, partook in multiple years of fieldwork in Dinosaur Provincial Park, Grande Prairie, Mongolia, and other places, and helped develop and deliver the Massive Open Online Course Dino 101.

Scott is originally from North Carolina and completed an undergraduate degree at Macalester College in St. Paul, Minnesota. His undergrad research included palaeoecology assessments of Triceratops-tooth-rich microsites in the Lance Formation of Wyoming, an evaluation of the relationship between foot size (relative to body mass) and habitat preference based on footprints of present African megafauna measured on the Serengeti Plain of Tanzania, and a senior honors project on the Ediacaran (Precambrian) fauna of the Boston Basin. Scott completed a MSc and then PhD with Specialization in Systematics and Evolution in 2011 and 2016, respectively, at the University of Alberta. He stayed on as a Postdoctoral Fellow until becoming an assistant professor at the College of Charleston and head curator of its Mace Brown Museum of Natural History in South Carolina.
