Philip Reese Bjork is an American geologist and paleontologist known for his work in unearthing dinosaur species in America.
Career
Bjork received his undergraduate degree at the University of Michigan.[1] Bjork's Master's thesis was on the vertebrate fossils of the Slim Buttes.[2] He was a professor at the South Dakota School of Mines and Technology[1] in Rapid City, South Dakota, as well as serving as director of their Museum of Geology[3] from 1975 to 2000.[2] His academic focus was on Cretaceous dinosaurs and mammals from the Cretaceous and early Cenozoic.
Highlights
- 1975
