Why Is James Hopson Influential?

(Suggest an Edit or Addition)

According to Wikipedia, James Allen Hopson is an American paleontologist and professor at the University of Chicago. His work has focused on the evolution of the synapsids , and has been focused on the transition from basal synapsids to mammals, from the late Paleozoic through the Mesozoic Eras. He received his doctorate at Chicago in 1965, and worked at Yale before returning to Chicago in 1967 as a faculty member in Anatomy, and has also been a research associate at the Field Museum of Natural History since 1971. He has also worked on the paleobiology of dinosaurs, and his work, along with that of Peter Dodson, has become a foundation piece for the modern understanding of duckbill crests, social behavior, and variation.
