Henry P. Elmer
In 1928, a rancher near Hagerman, Idaho, stumbled onto a fossil deposit that would eventually yield more than two hundred skeletons of a single extinct species, the largest concentration of fossil horses ever found in one place. That animal, Equus simplicidens, is now recognized as one of the earliest true representatives of the genus Equus, and its remains have become central to the scientific understanding of how the modern horse family evolved.Hagerman Horse traces the full natural history of this Pliocene-era species, from its evolutionary origins among earlier horse lineages to its physical characteristics, likely coloring, and life in the grassland and floodplain ecosystems of ancient Idaho roughly three and a half million years ago. Henry P. Elmer draws on decades of paleontological research conducted at the Hagerman Fossil Beds National Monument, now a protected U.S. National Park Service site, to explain how this discovery changed scientific thinking about horse evolution and the deep fossil record of the American West.The book examines the anatomical evidence that links Equus simplicidens to both earlier ancestors and later horse species, the climate and habitat conditions of the Pliocene epoch that shaped its evolution, and the environmental changes that eventually contributed to its extinction. It also explores the broader significance of the Hagerman fossil beds as a scientific resource, and what the site continues to teach paleontologists about mammalian evolution in North America.Written in a clear, narrative style accessible to general readers as well as students of paleontology, geology, and evolutionary biology, Hagerman Horse offers a complete, well-researched account of a species that stood at a critical branching point in horse evolution, long before horses as we know them existed anywhere in the world.GET YOUR BOOK NOW!
