Reviews

"These bizarre beasts are wonderful exemplars of parallel evolution, controversial in their implications for competition/extinction... and just plain intriguing!" Donald Prothero, author of After the Dinosaurs: The Age of Mammals "The history of the South American megafauna is a fascinating topic. For much of the Cenozoic Era South America was an island continent in which the carnivores were all marsupials and the herbivores were primitive ungulates that evolved into forms functionally similar to unrelated animals found elsewhere in the world. [They] were a unique blend of indigenous and immigrant animals that had apparently reached equilibrium in the wake of the Great American Interchange. When and why many of them subsequently went extinct has yet to be fully resolved." John Harris, Chief Curator of the George Page Natural History Museum
