Origins of the Sphinx , co-authored with my friend and colleague Robert Bauval, makes the case, based on multiple lines of evidence including geological and seismic analyses, astronomical analyses, and interpretations of ancient Egyptian texts , that the origins of the Great Sphinx go back prior to the end of the last ice age that is, before circa BCE.
I am proud to add that my wife Katie designed the photo insert and co-designed the book's beautiful cover. The question is no longer whether they are right but where archaeology should go from here. We discuss the serious scientific studies of the paranormal and include selections from fourteen seminal papers, through , by major figures in the field, plus pages of commentary.

I discuss the physical structure of the Great Pyramid and various theories and interpretations as to why it was built and when. Among other things, I believe that the nineteenth-century British astronomer Richard Proctor may have been correct when he hypothesized that the base or lower portion of what was to become the Great Pyramid served as an astronomical observatory before the superstructure was built.
Also published in Russian and Spanish. After critically analyzing the evidence, I have come to the conclusion that there was contact across both the Atlantic and Pacific Oceans in ancient times. In Voyages I also discuss the impacts and close flybys of comets in historic and prehistoric times that may have affected early civilizations and perhaps spurred long-range migrations. I also discuss the end of the last Ice Age, the rising sea levels at that time, and the origins of civilization.
Also published in Japanese, Italian, and Spanish. The issues facing us today, be they global warming, the depleting ozone layer, the controversy over nuclear power, or the continuing problems of water pollution and solid waste disposal, are headline news. Environmental Science: Systems and Solutions, Fourth Edition, offers the basic principles necessary to understand and address these multi-faceted and often very complex current environmental concerns. The book provides a comprehensive overview and synthesis of environmental science and provides the basic factual data necessary to understand the environment as it is today.
It is important that students understand how various aspects of the natural environment interconnect with each other and with human society. Using a systems approach, the authors have organized complex information in a way that highlights these connections in a fair and unbiased fashion. A Study Guide is incorporated at the end of each chapter to help reinforce concepts and provide a clear overview of material. Native to all continents except Australia and Antarctica, they include not only even-toed artiodactyls pigs, hippos, camels, deer, antelopes, giraffes, sheep, goats, and cattle and odd-toed perissodactyls horses and rhinos , but also tethytheres elephants and their aquatic relatives, manatees and seas cows and cetaceans whales and dolphins , which descended from hoofed land mammals.
Recent paleontological and biological discoveries have deepened our understanding of their evolution and in some cases have made previous theories obsolete. Prothero and Robert M. Schoch present a compelling new evolutionary history of these remarkable creatures, combining the latest scientific evidence with the most current information about their ecology and behavior.
Using an approach based on cladistics, the authors consider both living and extinct ungulates. Included in their discussion are the stories of rhinos, whose ancestors include both dinosaur-sized hornless species and hippo-like river waders; elephants, whose earliest ancestors had neither tusks nor trunks; and whales, whose descent from hoofed mesonychids has never properly been described for the lay audience.
Prothero and Schoch also update the evolutionary history of the horse, correcting the frequent errors made in textbooks and popular works, and they make available to the general public new evidence about the evolution of camels, horned antelopes, and cattle. In addition, they raise important conservation issues and relate anecdotes of significant fossil finds. Scientifically accurate and up to date, generously illustrated, and clearly written, Horns, Tusks, and Flippers is a useful and much-needed resource for specialists in the fields of paleontology, zoology, ecology, and evolutionary biology, as well as for general readers interested in learning more about the story of life on Earth.
A technical edited volume that compiles a number of important contributions, by specialists in the field, concerning the evolution of vertebrates, from fishes to mammals. Publisher's description excerpt : This new treatise [new in ] is comprised of 24 papers covering virtually every recent development regarding fossil horses, rhinos, tapirs, and their extinct relatives.
It includes materials currently available in no other reference, such as information on the oldest known rhino and the oldest known perissodactyl, as well as papers debunking myths about the evolution of horses, and strong evidence that hyraxes are not related to elephants.
The summary chapter includes useful charts which show the relationships of all perissodactyl genera, their distribution in time and space, and a new classification of the order.
