Pleistocene Pocket Gophers from San Josecito Cave, Nuevo Leon, Mexico

A scientific publication written in the mid-20th century. The book focuses on the paleontological findings of pocket gopher remains in San Josecito Cave, offering insights into the Pleistocene era's mammalian fauna, specifically geomyids. It serves as a valuable resource for understanding the evolutionary history and distribution of these creatures in northeastern Mexico. The content of the book presents detailed descriptions and analyses of various species of pocket gophers discovered in San Josecito Cave, including their characteristics, comparisons with modern relatives, and implications for paleoclimatic conditions. Russell examines well-preserved fossil specimens and discusses the ecological context of these animals, suggesting they lived during a time when the area had more tropical conditions. The findings not only illuminate the specific species found but also contribute to the broader understanding of mammalian evolution and climate change during the Pleistocene epoch.
