It took centuries of scientific effort--and a lot of luck--to discover and establish the diversity of dinosaur species we now know. How did we learn that Triceratops had three horns? Why don't many paleontologists consider Brontosaurus a valid species? What convinced scientists that modern birds are relatives of ancient Velociraptor? In this book, Donald R. Prothero tells the fascinating stories behind the most important fossil finds and the intrepid...

Takes the reader back 210 million years to the age when dinosaurs first evolved and describes the world of that time.

Three living species of wild Canis occur in North America, Canis latrans, the coyote, with 19 subspecies; C. rufus, the red wolf, with 3 subspecies; and C. lupus, the gray or timber wolf, with 24 subspecies (see revisions of Goldman, 1937, 1944, ; Anderson, 1943; Jackson, 1951). Although this taxonomic arrangement has been generally accepted, some questions have recently arisen concerning matters not fully explained by the revisions, and certain newly...

"Perhaps nudged over the evolutionary cliff by a giant boloid striking the Earth, the incredible and fascinating group of animals called dinosaurs (except for their feathered descendants) became extinct some 65 million years ago. In their place evolved an enormous variety of land creatures, especially the mammals, which in their way were every bit as remarkable as their Mesozoic cousins." "The Age of Mammals, the Cenozoic Era, has never had its Jurassic...
