Book Description
The horse has frequently been used as a classic example of long-term evolution because it possesses an extensive fossil record. This book synthesizes the large body of data and research relevant to an understanding of fossil horses from perspectives such as biology, geology, paleontology.

Book Description
This book provides an update on the phylogeny, systematics and ecology of horses in South America based on data provided over the past three decades. The contemporary South American mammalian communities were shaped by the emergence of the Isthmus of Panama and by the profound climatic oscillations during the Pleistocene. Horses were a conspicuous group of immigrant mammals from North America that arrived in South America during the Pleistocene. This group is represented by 2 genera, Hippidion and Equus, which include small species (Hippidion devillei, H. saldiasi, E. andium and E. insulatus) and large forms (Equus neogeus and H. principale). Both groups arrived in South America via 2 different routes. One model designed to explain this migration indicates that the small forms used the Andes corridor, while larger horses used the eastern route and arrived through some coastal areas. Molecular dating (ancient DNA) suggests that the South American horses separated from the North American taxa (caballines and the New World stilt-legged horse) after 3.6 - 3.2 Ma, consistent with the final formation of the Panamanian Isthmus. Recent studies of stable isotopes in these horses indicate an extensive range of 13C values cover closed woodlands to C4 grasslands. This plasticity agrees with the hypothesis that generalist species and open biome specialist species from North America indicate a positive migration through South America.

Book Description
The landscape of southwestern Wyoming around the ghost town of Fossil is beautiful but harsh; a dry, high mountain desert with cool nights and long, cold winters inhabited by a sparse mountain desert community. But during the early Eocene, more than fifty million years ago, it was a subtropical lake, surrounded by volcanoes and forests and teeming with life. Buried within the sun-baked limestone is spectacular evidence of the lush vegetation and plentiful fauna of the ancient past, a transitional ecosystem giving us clues to how North America recovered from a great extinction event that wiped out dinosaurs and the majority of all species on the planet. Paleontologists have been conducting excavations at Fossil Butte for more than 150 years, and with The Lost World of Fossil Lake, one of the world’s leading experts on the fossils from this spectacular locality takes readers on a fascinating journey through the history of the discovery and exploration of the site. Deftly mixing incredible color photographs of the remarkable fossils uncovered at the site with an explanation of their evolutionary significance, Grande presents an unprecedented, comprehensive portrait of the site, its treasures, and what we’ve learned from them. Grande presents a broad range of fossilized organisms from Fossil Lake—from single-celled algae to palm trees to crocodiles—and together they make this long-extinct community come to life in all its diversity and splendor. A field guide and atlas round out the book, enabling readers to identify and classify the majority of the known fossils from the site. Lavishly produced in full color, The Lost World of Fossil Lake is a stunning reminder of the intellectual and physical beauty of scientific investigation—and a breathtaking window onto our planet’s long-lost past.
