Archosaurs, an important reptile group that includes today's crocodiles and birds, arose during the Triassic in the aftermath of the greatest mass extinction of all time. In the last 20 years, our understanding of the early evolution of the group has improved substantially with the discovery of new fossils and species of early archosaurs and their closest relatives, a better understanding of the relationships of these animals, and new insights into their palaeobiology. In order to synthesize these new data, researchers of early archosaurs from around the world met at the first symposium of early archosaur evolution at the IV Congreso Latinoamericano de Paleontología de Vertebrados (September 2011) in San Juan, Argentina. This symposium facilitated collaboration and strove to paint a better understanding of these extraordinary animals. The resultant body of work is a state-of-the-art examination of early archosaur groups and their close relatives including historical, anatomical, biogeographical, evolutionary and palaeobiological data. This contribution furthers our knowledge of the anatomy, relationships, and palaeobiology of species-level taxa as well as more global patterns of archosaur evolution during the Triassic -- P. 4 of cover.

Provides an introduction to dinosaurs and other ancient animals that existed at the same time in the prehistoric world.
This book is about the time when giant reptiles ruled the world, on land (dinosaurs), in the sea (sea monsters), and in the air (pterosaurs). It was a unique period, never to be repeated once mammals became the dominant tetrapods. Birds and mammals first appeared as well, but remained insignificant until these reptiles were already extinct. The book is designed for a wide audience of age groups, ranging in age from seven years (my grandson Jake) to those of us at 77 (my age). The approach is holistic. For example, it describes relevant concepts within the geosciences, including how fossils record the history of life and how radioactivity provides us with the numerical ages of this history. Also, it describes the significant influence of mass extinctions and of the plate tectonic rearrangement of the continents. The book is well-illustrated. There are more than 65 accurate drawings and additional cartoons.They are used to illuminate the written narrative. Enjoy.
A comprehensive e-guide to dinosaurs and prehistoric animals and the world they inhabited millions of years ago. Includes more than 700 full-color illustrations, this definitive e-guide paints a vivid portrait of extraordinary dinosaurs and prehistoric animals, and the ecosystems they lived in millions of years ago. This e-guide features authoritative text, crystal-clear illustrations, and a straightforward approach to revealing the fascinating lives and habitats of dinosaurs, pterosaurs, marine reptiles, and prehistoric beasts. The introductory section explains classification systems, geological timelines, the evolution of the dinosaurs, and how fossils form and are discovered by paleontologists. For ease of reference, the main body of the ebook is divided into three sections: the Precambrian and Paleozoic eras, when animals first began evolving; the Mesozoic era, which saw the flourishing and eventual extinction of the dinosaurs; and the Cenozoic era, when giant mammals walked the Earth. Each section is broken down into its geological time periods, and, within these, the species are organized according to habitat--whether they lived on land, in the water, or in the air. There are detailed profiles of 200 dinosaurs and other ancestors of modern animals. Each entry combines a precise, jargon-free description with full-color illustrations, skeletons, and replica models, annotated to showcase the unique features of the species. Maps show where each animal's fossils have been found, and many profiles are supported by photographs to show actual excavation sites.
Dinosaurs are one of the most spectacular groups of animals that have ever existed. Many were fantastic, bizarre creatures that still capture our imagination: the super-predator Tyrannosaurus, the plate-backed Stegosaurus, and the long-necked, long-tailed Diplodocus. Dinosaurs: The Ultimate Guide to How They Lived taps into our enduring interest in dinosaurs, shedding new light on different dinosaur groups. Leading paleontology experts Darren Naish and Paul Barrett trace the evolution, anatomy, biology, ecology, behavior, and lifestyle of a variety of dinosaurs. They also remind us that dinosaurs are far from extinct: they present evidence supporting the evolution of dinosaurs to birds that exist today as approximately ten thousand different species. Throughout their narrative Naish and Barrett reveal state-of-the-art new findings shaping our understanding of dinosaurs. Readers will discover, for example, how the use of CT-scanning enables scientists to look inside dinosaur skulls, thus gaining new insight into their brains and sense organs. Dinosaurs is a must-have for all those wanting to keep up to date about these dynamic, complicated creatures.
Text and photographic illustrations describe the characteristics and habits of several dinosaurs and other prehistoric reptiles that roamed the earth during the Cretaceous Period.
