Sinclair Oil Corporation was an American petroleum corporation founded by Harry F. Sinclair on May 1, 1916. The Sinclair Oil and Refining Corporation amalgamated the assets of 11 small petroleum companies.[3] Originally a New York corporation, Sinclair Oil reincorporated in Wyoming in 1976.[4] The corporate logo featured the silhouette of a large green Apatosaurus dinosaur, based on the then-common idea that oil deposits beneath the earth came from the dead bodies of dinosaurs.
Sinclair was ranked as one of the largest privately owned American corporations.[1] It owned and operated refineries, gas stations, hotels, a ski resort, and a cattle ranch.[1]
