This field book contains notes on the paleontological specimen and geology of the Devonian period in Iowa, Michigan, Illinois, Missouri, Wisconsin, Minnesota, and Ontario taken around 1934-1940. Locations Cooper visits include Roger City (Michigan), Stony Point (Ontario), Partridge Point, Quasqueton (Iowa), Holts Summit (Missouri), and other areas. Cooper describes stratigraphy of the locations, often providing color and consistency of shale in which fossils are found. Fossils vary greatly, but examples of fossils noted are marine mollusks falling into the cephalopods or gastropod class and cnidaria. Also included are several maps that are annotated and have numeric or alpha numeric codes that Cooper uses in his field notes to refer to locations. Page numbers for these field notes are 0001- 0310.
