Life

Stephenson studied at Johns Hopkins University and was after completing his doctorate from 1907 on the US Geological Survey . First he dealt there with the geology and hydrology of the coastal plain of North Carolina and its Cretaceous fossils and then with the Cretaceous fauna and stratigraphy of the entire Atlantic and Gulf coast of the USA. He also proposed new concepts for stratigraphic subdivision (various fauna zones). He later dealt primarily with the stratigraphy of the Upper Cretaceous in Texas. He also worked for oil companies as a consultant, for example for chalk stratigraphy in Mexico and Venezuela. In 1922 he succeeded T. Wayland Vaughan as head of the Coastal Plains department (Coastal Plains, both Atlantic and Gulf Coast), which he stayed until 1936 because he wanted to focus exclusively on research. He retired in 1947, but continued to work at the USGS on a voluntary basis and held various teaching positions. In 1949 he went to Japan for the US Army to help find oil.

In 1941 he was President of the Paleontological Society and in 1926 Vice President of the Washington Academy of Sciences. In 1952 he received the Mary Clark Thompson Medal .
