http://www.pgdp.net  a"Evolution and Classification of the Pocket Gophers of the Subfamily Geomyinae" by Robert J. Russell is a scientific publication written in the late 20th century. The work focuses on the evolutionary history, anatomical features, and classification of pocket gophers belonging to the subfamily Geomyinae. It provides an in-depth analysis of fossil records and modern species, illustrating the taxonomic intricacies and evolutionary trends within this group of rodents.  The opening of this publication introduces the background and significance of the research, highlighting the importance of previous studies on pocket gophers, particularly noting C. Hart Merriam's earlier work in 1895. Russell discusses the limitations Merriam faced due to access to fossil specimens, suggesting that a more thorough examination of fossils can greatly influence our understanding of the evolutionary pathway of Geomyinae. Additionally, the introduction alludes to the book's comprehensive approach in examining various anatomical characteristics used for classification, laying the groundwork for the detailed exploration of evolutionary changes and phylogenetic relationships among modern and fossil pocket gophers.
