James Allen Hopson (* 27. August 1935 in New Haven (Connecticut) ) is an American vertebrate - paleontologist .

life and work

Hopson graduated from Yale University with a bachelor's degree in 1957 and received his doctorate in paleontology from the University of Chicago in 1965 . From 1963 to 1967 he was at the Peabody Museum of Natural History and in 1967 he was assistant professor and in 1986 professor at the University of Chicago. Since 1971 he has also been a Research Associate at the Field Museum of Natural History in Chicago.

He is mainly concerned with the evolutionary history of synapsids , mammal-like reptiles ( therapsids ) and the origin of mammals. Accordingly, his focus is on the Permian and Triassic periods , and since many finds of mammalian reptiles from this period come from South Africa, he traveled there frequently. He also dealt with hadrosaurs like Parasaurolophus and the function of their bone crest on the skull.

In 1984 he was president of the Society of Vertebrate Paleontology and became an honorary member in 2008. In 2015 he received their Romer-Simpson Medal .
