00 This study presents current data on vertebrate survival and extinction across the Cretaceous-Tertiary boundary in Montana. Nearly all the common taxa of reptiles (except dinosaurs), amphibians, and fish survived the end of the Cretaceous Period; extinctions were concentrated among rare groups and those found in near-shore habitats. The author concludes that ocean regression and climatic deterioration may explain these selective extinction patterns better than catastrophic hypotheses.

The Grand Staircase-Escalante National Monument is the location of one of the best-known terrestrial records for the late Cretaceous. Prior fieldwork confirmed the richness of the area, but a major effort begun in the new century has documented over 2,000 new vertebrate fossil sites, provided new radiometric dates, and identified five new genera of ceratopsids, two new species of hadrosaur, a probable new genus of hypsilophodontid, new pachycephalosaurs and ankylosaurs, several kinds of theropods (including a new genus of oviraptor and a new tyrannosaur), plus the most complete specimen of a Late Cretaceous therizinosaur ever collected from North America, and much more. The research documented in this book is rewriting our understanding of Late Cretaceous paleobiogeography and dinosaur phyletics. At the Top of the Grand Staircase: The Late Cretaceous of Southern Utah is a major stepping stone toward a total synthesis of the ecology and evolution of the Late Cretaceous ecosystems of western North America.

“Excellent . . . Those who are interested in vertebrate paleontology or in the scientific history of the American midwest should really get a copy.” —PalArch’s Journal of Vertebrate Paleontology Revised, updated, and expanded with the latest interpretations and fossil discoveries, the second edition of Oceans of Kansas adds new twists to the fascinating story of the vast inland sea that engulfed central North America during the Age of Dinosaurs. Giant sharks, marine reptiles called mosasaurs, pteranodons, and birds with teeth all flourished in and around these shallow waters. Their abundant and well-preserved remains were sources of great excitement in the scientific community when first discovered in the 1860s and continue to yield exciting discoveries 150 years later. Michael J. Everhart vividly captures the history of these startling finds over the decades and re-creates in unforgettable detail these animals from our distant past and the world in which they lived—above, within, and on the shores of America’s ancient inland sea. “Oceans of Kansas remains the best and only book of its type currently available. Everhart’s treatment of extinct marine reptiles synthesizes source materials far more readably than any other recent, nontechnical book-length study of the subject.” —Copeia “[The book] will be most useful to fossil collectors working in the local region and to historians of vertebrate paleontology . . . Recommended.” —Choice

This study identifies the fall of dinosaurs as the factor that allowed mammals to evolve into the dominant tetrapod form. It refutes the single-cause impact theory for dinosaur extinction and demonstrates that multiple factors--massive volcanic eruptions, loss of shallow seas, and extraterrestrial impact--likely led to their demise. While their avian relatives ultimately survived and thrived, terrestrial dinosaurs did not. Taking their place as the dominant land and sea tetrapods were mammals, whose radiation was explosive following nonavian dinosaur extinction. The author argues that because of dinosaurs, Mesozoic mammals changed relatively slowly for 145 million years compared to the prodigious Cenozoic radiation that followed. Finally out from under the shadow of the giant reptiles, Cenozoic mammals evolved into the forms we recognize today in a mere ten million years after dinosaur extinction.

Toward the end of the Age of Dinosaurs, during a time known as the Late Cretaceous, a new type of giant predator appeared along the southern coasts of North America. It was a huge species of crocodylian called Deinosuchus. Neither a crocodile nor an alligator, it was an ancestor of both modern groups; it reached weights of many tons and it had some features unique to its own species. Average-sized individuals were bigger than the carnivorous dinosaurs with which they co-existed; the largest specimens were the size of a T-rex. King of the Crocodylians, the biography of these giant beasts, tells the long history of their discovery and reports on new research about their makeup. The book also deals with the ancient life and geology of the coastal areas where Deinosuchus thrived, its competitors, and its prey, which probably included carnivorous dinosaurs. There is also detailed discussion of the methods used to determine the size of these giant animals, the dating of the fossils, the nature of their living environments, and how we know who ate whom 80 million years ago.
