Extinction and Radiation
How the Fall of Dinosaurs Led to the Rise of Mammals
Archibald refutes the widely accepted single-cause impact theory for dinosaur extinction. He 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.
Archibald 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.
Extinction and Radiation is the first book to convincingly link the rise of mammals with the fall of dinosaurs. Piecing together evidence from both molecular biology and the fossil record, Archibald shows how science is edging closer to understanding exactly what happened during the mass extinctions near the K/T boundary and the radiation that followed.
About the Author
"A learned essay, written clearly and attractively for students and the public."—Michael J. Benton, Cambridge Archaeological Journal
"What makes Archibald's book a highly recommendable example of the scientific process is that the author carefully lays out all the paleontological evidence available to him and uses that evidence to evaluate the many possible explanations of the extinction, discussing the strengths, weaknesses, and limitations of each explanation in the process."—Reports of the National Center for Science Education
"This is a learned essay, written clearly and attractively for students and the public."—Michael J. Benton, Geological Magazine
"An excellent compendium of the current state of paleontological knowledge about the contemporaneous histories of these two groups."—Mark A. McPeek, Quarterly Review of Biology
"A highly recommendable example of the scientific process is that the author carefully lays out all the paleontological evidence available to him and uses that evidence to evaluate the many possible explanations of the extinction."—P David Polly, Reports of the National Center for Science Education
"The book itself is a handsome quarto volume illustrated by good drawings and graphs. It will be most useful to paleontologists, evolutionary biologists and biogeographers. It will stand as a good example of what can be accomplished in academia."—Priscum, Newsletter of the Paleontological Society
"Books like Extinction and Radiation enable interested members of the general public to share in the excitement of the arugment."—Nicholas Gould, International Zoo News
"This volume is logically organized, easily readable, and a noteworthy synthesis of the current state of our knowledge of the disappearance of nonavian dinosaurs and mammalian radiation. It is a useful reference from an acknowledged authority in the field and valuable for students, teachers, scientists, and all people interested in the evolution and fate of our planet and its biodiversity."—Journal of Mammalogy
"David Archibald is one of the most knowledgeable people in the world about extinctions, as well as the fairest analyst of their patterns and causes. In this book he invites his readers to consider not just dinosaurs but all the animals that lived at the end of the Age of Dinosaurs. He provides the clearest picture yet of this extremely complex time in the history of life. Anyone interested in paleontology or extinction, especially those who think they already know what did in the dinosaurs, should read this book."—Kevin Padian, University of California, Berkeley
