The Beginning of the Age of Mammals

by Kenneth D. Rose
Baltimore (MD): The Johns Hopkins University Press, 2006. 448 pages.

The Beginning of the Age of Mammals provides a magisterial (and marvelously illustrated) survey of the evolution of mammals, beginning with their origin in the Mesozoic and continuing through the early Cenozoic. "The first comprehensive synthesis of mammal evolution in more than 20 years," writes the reviewer for the Quarterly Review of Biology: "It is arguably the most significant contribution to the field since George Simpson's classic work Principles of Classification and a Classification of Mammals." Rose is a professor at the Center for Functional Anatomy and Evolution at the Johns Hopkins University School of Medicine.
