A New Species of Heteromyid Rodent from the Middle Oligocene of Northeast Colorado with Remarks on the Skull

** "A New Species of Heteromyid Rodent from the Middle Oligocene of Northeast Colorado with Remarks on the Skull" by Edwin C. Galbreath is a scientific report detailing the unearthing of a new rodent species, "Heliscomys tenuiceps," dating back to the Middle Oligocene epoch in Northeast Colorado. The report uses fossil evidence to deliver meticulous descriptions and anatomical discoveries that significantly enhance our comprehension of rodent evolution throughout this geological era. It presents an intensive examination of the new species, built upon the skull and teeth discovered and outlines the size, distinctive features, and anatomical specifics compared to related species from the time. The report carefully considers the skull's construction, noting observations regarding the nasal, frontal bones, and provides the skull and teeth measurements while showcasing the species' unique attributes. The find ultimately illuminates the Heteromyids' evolutionary path and proposes that "H. tenuiceps" displays qualities related to earlier and later forms of rodents, classifying it as an important paleontological find. **
