Everett C. Olson

Source: Wikipedia, the free encyclopedia.

Everett Claire Olson (November 6, 1910 – November 27, 1993) was an American

paleontologist, and geologist noted for his seminal research of origin and evolution of vertebrate animals.[1][2][3]
Through his research studying terrestrial vertebrate fossils he identified intervals of extinction in 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".[10][8][11][12]
Some of his other notable research also included the taxa Slaugenhopia,[13] Trimerorhachis, and Waggoneria.[14]

Olson was a former chair of the department of Biology at the

UCLA,[1][2]
a member of the National Academy of Sciences,[1][2] a recipient of Paleontological Medal of the Paleontological Society (1987),[2] the first recipient of the Romer-Simpson Medal of the Society of Vertebrate Paleontology,[2] a CSEOL Distinguished Scientist (1991).[2] University of California said that Olson "was an internationally recognized pioneer in studies of the origin and evolution of vertebrate animals".[2] The University of Chicago said that he "carried out pioneering research on the evolution of terrestrial ecosystems".[3] The National Academy of Sciences said that he ranked "among the great vertebrate paleontologists of the twentieth century".[1]

Life and career

Olson was born in Waupaca, Wisconsin and grew up in Hinsdale, Illinois. Olson received his undergraduate and graduate degrees, including Ph.D. in geology (1935) from the University of Chicago.
