Why Is Everett C. Olson Influential?
(Suggest an Edit or Addition)According to Wikipedia, Everett Claire Olson was an American zoologist, paleontologist, and geologist noted for his seminal research of origin and evolution of vertebrate animals. Through his research studying terrestrial vertebrate fossils he identified intervals of extinction in the Permian and Triassic. He developed the concept of chronofauna, which he defined as "a geographically restricted, natural assemblage of interacting animal populations that has maintained its basic structure over a geologically significant period of time". He also proposed stratigraphic correlations between North American and Russian vertebrate-bearing strata for which additional support was found much later. The drop in terrestrial vertebrate diversity he proposed in at the end of the Kungurian stage of the Permian period that occurred 270 million years ago now carries his name - Olson's Extinction. Alternatively, some scientists think that the change was gradual but that it looks abrupt because of a gap in the fossil record, called "Olson's Gap". Some of his other notable research also included the taxa Slaugenhopia, Trimerorhachis, and Waggoneria.
