About This Book

The work presents a comprehensive morphological and paleontological analysis of North American pocket gophers (subfamily Geomyinae), using dental and cranial characters—especially molar prism patterns, enamel, incisors, and masseteric features—to interpret evolutionary trends from the Miocene through the Pleistocene. It reviews fossil occurrences, revises classification at the genus and subgenus levels, describes extant and extinct genera, and proposes phylogenetic relationships and biogeographic patterns. Illustrations, specimen-based comparisons, and literature citations support taxonomic decisions and phyletic reconstructions.
