Horns and Beaks completes Ken Carpenter's series on the major dinosaur types. As with his volumes on armored, carnivorous, and sauropodomorph dinosaurs, this book collects original and new information, reflecting the latest discoveries and research on these two groups of animals. The Ornithopods include Iguanodon, one of the first dinosaurs ever discovered and analyzed, and perhaps the most common and best-documented group, the hadrosaurs or "duckbilled dinosaurs." The Ceratopsians include Triceratops, known for its distinctive three-horned skull and protective collar.

The meat-eating dinosaurs, or Theropoda, include some of the fiercest predators that ever lived. Some of the group s members survive to this day as birds. The theropod/bird connection has been explored in several recent works, but this book presents 17 papers on a variety of other topics. It is organized into three parts. Part I explores morphological details that are important for understanding theropod systematics. Part II focuses on specific regions of theropod anatomy and biomechanics. Part III examines various lines of evidence that reveal something about theropods as living...

Western doctors working in Asia after 1870 saw it as the major disease in native armed forces and prisons. It was at first attributed to miasms (poisonous vapors...

With its massive head, enormous jaws, and formidable teeth, Tyrannosaurus rex has long been the young person's favorite creepy carnivore in the Mesozoic zoo. Nor has T. rex been ignored by the scientific community, as this new collection amply demonstrates. Scientists explore such questions as why T. rex had such small forelimbs; how the dinosaur moved; what bone pathologies tell us about life in the Cretaceous; and whether T. rex was a predator, a scavenger, or both. There are reports on newly discovered skeletons, on variation and sexual dimorphism, and how the big beasts chewed. The...

The large, quadrupedal herbivores known as sauropods were widespread around the planet from the Jurassic to the end of the Cretaceous. With the longest necks and tails of all of the dinosaurs, some sauropods were 40 meters in length and weighed upwards of 100,000 kilograms, more than 20 tons. The popular image of these lumbering giants, placidly consuming ferns has been greatly revised in recent years. New discoveries and new theories about behavior and physiology have continued to enrich the study of these remarkable beasts. This book presents 21 new studies of the sauropods. The book is...

This overview of dinosaur discoveries in Mexico synthesizes current information about the geography and environment of the region during the Mesozoic when it was the western margin of the ancient continent of Pangea. The book summarizes research on various groups, including turtles, lepidosauromorphs, plesiosaurs, crocodyliforms, pterosaurs, and last but not least, dinosaurs. In addition, chapters focus on trackways and other trace fossils and on K/P boundary (the Chicxulub crater, beneath the Gulf of Mexico, has been hypothesized as the site of the boloid impact that killed off the...
