This book assembles information on the fish fauna of South Dakota into a conveniently usable form. Ninety-three species are described with precise data on distribution and measurements. Additionally, this book attempts (1) to collect and identify published records of South Dakota fishes, (2) to present keys for the identification of fishes known or expected to occur in South Dakota, (3) to record original distributional data based on 137 fish collections taken throughout the state, (4) to solve some problems involving the systematic status of certain South Dakota species, (5) to clarify or extend information on the distribution of several species in the adjoining Plains area, and (6) to determine the geographic sources of origin of South Dakota fishes and to interpret routes of postglacial dispersal.

Excerpt from Occasional Papers of the Museum of Zoology, University of Michigan: Numbers 62-90; 1918-1920 In 1913 an expedition from the University of Michigan excavated the Brier Creek Bone Bed in Archer County, Texas, discovered the previous year. From this bone bed over fifteen hundred specimens, mostly of isolated bones, were recovered. From this large amount of material two skeletons have so far been restored showing the complete skeletal anatomy of the great lizard-like Permo-Carboniferous reptiles Dimetrodon (completed in 1915 and now in the Museum of Zoology of the University) and Edaphosaurus, just completed. The genus Edaphosaurus has been one of the most puzzling forms of reptilian life of the late Paleozoic and the completion of a mount showing of its characters is the final result of many collecting trips and trial mounts.
