This volume features a collection of papers originally published between July 10, 1924, and August 3, 1927, and edited by Eugene S. McCartney. Most, but not all, of the contributors were members of the faculties or graduates of the University of Michigan who published on their findings while examining fossils and rock formations. Many of the articles discuss findings from the state of Michigan, including "Occurrence of the Collingwood Formation in Michigan."
