Robert Carroll is a professor emeritus at McGill University, was the long-time director of the Redpath Museum and chairman of the Department of Biology, and is a fellow of the Royal Society of Canada. He is among the world’s most highly regarded experts on the evolution of amphibians and reptiles. Carroll is the author of several books, including Vertebrate Paleontology and Evolution.
For nearly 100 million years amphibians and their ancestors dominated the terrestrial and shallow water environments of the earth. Archaic animals with an amphibious way of life gave rise not only to modern frogs, salamanders, and caecilians but also to the ancestors of reptiles, birds, and mammals.
In this landmark publication, one of the leading paleontologists of our time explores a pivotal moment of vertebrate evolution, the rise of amphibians. Synthesizing findings from the rich and highly diverse fossil record of amphibians, Robert Carroll traces their origin back 365 million years, when particular species of fish traveled down an evolutionary pathway of fin modification that gave rise to legs. This period of dramatic radiation was followed by a cataclysmic extinction 250 million years ago. After a long gap, modern amphibian groups gradually emerged. Now the number of amphibian species and individuals throughout the tropical and temperate regions of the earth exceeds that of mammals.
"The Rise of Amphibians" is documented with more than two hundred illustrations of fossil amphibians and sixteen exquisite color plates depicting amphibians in their natural habitats throughout their long existence. The most comprehensive examination of amphibian evolution ever produced, "The Rise of Amphibians" is an essential resource for paleontologists, herpetologists, geologists, and evolutionary biologists.
