Everett Claire Olson (November 6, 1910 – November 27, 1993) 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. 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, also termed "Olson's Gap". Some of his other notable research also included genus of Slaugenhopia genus of Trimerorhachis, and genus of Waggoneria.
