Book Description
The Ornithopoda, one of five suborders within the Ornithischia, was originally proposed by Marsh in 1881 to include those bipedal dinosaurs possessing a predentary bone fitted over the rostral end of the mandibles. Ornithopods as recognized today can be further characterized by moderately long facial skele tons equipped with well-developed, often toothless premaxillae and moderate to large external nares. Maxillary and dentary dentitions vary but usually consist of at least one replacement series beneath the functional set; some have many rows of successional teeth. Tooth morphology suggests ornithopods were suc cessful herbivores but, as will be discussed, the precise way(s) in which ornitho pods chewed their food, hence lending important information about their tro phic position, has not been settled. Postcranially, ornithopods show specializa tion for bipedality in hindlimb construction and lack well-developed protective structures on their flanks, back, and tail. The Ornithopoda can itself be divided into five families: Fabrosauridae, He terodontosauridae, Hypsilophodontidae, 19uanodontidae, and Hadrosauridae (subdivided into the subfamilies Hadrosaurinae and Lambeosaurinae). Both fabrosaurids and heterodontosaurids, first known from the Late Triassic and Early Jurassic of Argentina and South Africa, were small animals differing in details of cranial, dental, and appendicular anatomy. Fabrosaurids are be lieved to represent the basal ornithopod stock (Galton 1972, 1978; Thulborn 1970a, 1972). During the Jurassic, ornithopods underwent major radiations that included the medium- to large-sized Hypsilophodontidae and the large bodied Iguanodontidae, both of which survived into the Cretaceous.

Book Description
A comprehensive study of the Late Cretaceous, duck-billed dinosaur, featuring insights on its origins, anatomy, and more. Hadrosaurs—also known as duck-billed dinosaurs—are abundant in the fossil record. With their unique complex jaws and teeth perfectly suited to shred and chew plants, they flourished on Earth in remarkable diversity during the Late Cretaceous. So ubiquitous are their remains that we have learned more about dinosaurian paleobiology and paleoecology from hadrosaurs than we have from any other group. In recent years, hadrosaurs have been in the spotlight. Researchers around the world have been studying new specimens and new taxa seeking to expand and clarify our knowledge of these marvelous beasts. This volume presents the results of an international symposium on hadrosaurs, sponsored by the Royal Tyrrell Museum and the Royal Ontario Museum, where scientists and students gathered to share their research and their passion for duck-billed dinosaurs. A uniquely comprehensive treatment of hadrosaurs, the book encompasses not only the well-known hadrosaurids proper, but also Hadrosaouroidea, allowing the former group to be evaluated in a broader perspective. The 36 chapters are divided into six sections—an overview, new insights into hadrosaur origins, hadrosaurid anatomy and variation, biogeography and biostratigraphy, function and growth, and preservation, tracks, and traces—followed by an afterword by Jack Horner. “Well designed, handsome and fantastically well edited (credit there to Patricia Ralrick), congratulations are deserved to the editors for pulling together a vast amount of content, and doing it well. The book contains a huge quantity of information on these dinosaurs.” —Darren Naish, co-author of Tetrapod Zoology, Scientific American “Hadrosaurs have not had the wide publicity of their flesh-eating cousins, the theropods, but this remarkable dinosaur group offers unique opportunities to explore aspects of palaeobiology such as growth and sexual dimorphism. In a comprehensive collection of papers, all the hadrosaur experts of the world present their latest work, exploring topics as diverse as taxonomy and stratigraphy, locomotion and skin colour.” —Michael Benton, University of Bristol

Pages : 382
Book Description
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. Contributors are Michael K. Brett-Surman, Kathleen Brill, Kenneth Carpenter, Benjamin S. Creisler, Tony DiCroce, Andrew A. Farke, Peter M. Galton, David Gilpin, Thomas M. Lehman, Nate L. Murphy, Christopher J. Ott, Gregory S. Paul, Xabier Pereda Suberbiola, Albert Prieto-Marquez, Bruce Rothschild, José Ignacio Ruiz-Omeñaca, Darren H. Tanke, Mark Thompson, David Trexler, and Jonathan R. Wagner.
