Dinosaurs were a group of reptiles that lived on Earth millions of years ago. They were some of the largest animals to ever roam the planet, with some species growing to be as tall as a two-story building. Dinosaurs first appeared during the Mesozoic Era, which is sometimes referred to as the "Age of Reptiles." This era lasted from about 252 million years ago to 66 million years ago and was divided into three periods: the Triassic, Jurassic, and Cretaceous periods. During the Triassic period, the earliest dinosaurs evolved from smaller reptiles. These early dinosaurs were not very large, and they were not the dominant animals on Earth at the time. However, during the Jurassic and Cretaceous periods, dinosaurs became much larger and more diverse.

This 2005 edition of The Evolution and Extinction of the Dinosaurs is a unique, comprehensive treatment of this fascinating group of organisms. It is a detailed survey of dinosaur origins, their diversity, and their eventual extinction. The book can easily be used as a teaching textbook for a class, but it is also written as a series of readable, entertaining essays covering important and timely topics appealing to non-specialists and all dinosaur enthusiasts: birds as 'living dinosaurs', the new feathered dinosaurs from China, 'warm-bloodedness'. Along the way, the reader learns about dinosaur functional morphology, physiology, and systematics using cladistic methodology - in short, how professional paleontologists and dinosaur experts go about their work, and why they find it so rewarding. The book is spectacularly illustrated by John Sibbick, a world-famous illustrator of dinosaurs, commissioned exclusively for this book.

Suitable for children ages 7-10, this book includes information on various dinosaurs. It is divided into three sections by period: Triassic, Jurassic, Cretaceous.

"On the Wing is the first book to take a comprehensive look at the evolution of flight in all four groups of powered flyers: insects, pterosaurs, birds, and bats."--Book jacket.

Fossils no more, dinosaurs are brought back to life to challenge each other in epic battles. Dinosaurs from the Cretaceous period to the Jurassic period meet for the first time to test their strength in this high-interest read. Where else will dinosaur enthusiasts have a chance to see their favorite dinosaurs duke it out while learning about the adaptations that make them fierce competitors? This volume features, of course, the T-rex and many other lesser-known dinosaurs.

It is time for young Neffy to go for her first, beautifully illustrated solo flight--but she doesn't know how!

Step back in time 124 million years to Liaoning, China, and see what life was like in this ancient ecosystem. Follow several recently discovered dinosaur species through a typical day, as they feed, fight, hunt, and try to survive. Scientific sculptor and illustrator Gregory Wenzel takes readers inside the world of the feathered dinosaurs and sheds light on the link betweeen dinosaurs and birds.

This book synthesises the growing body of evidence which suggests that modern-day birds have evolved from theropod dinosaurs of prehistoric times. The author argues that the ancestor-descendant relationship can also be reversed.

"Inspired by the spectacular discoveries of the past two decades from the Age of Reptiles in China, Riddle of the Feathered Dragons explores how these miraculous fossils have transformed the contentious arena of bird and dinosaur evolution. Aside from being the most comprehensive discussion of these avian and associated discoveries, the author delves into the world of investigative journalism to expose the darker side of the world of fossil birds and dinosaurs. The book exposes the massive unfounded speculation that has characterized the field of vertebrate paleontology and published extensively in the world's most prestigious journals, including everything from supposed dinosaur protein to so-called feathered dinosaurs. The book questions the validity of the foundational tenets of the now "unquestionable orthodoxy" of bird and dinosaur evolution, including bird origins, feathered dinosaurs, flight origin from the ground-up and hot-blooded dinosaurs and their proteins. It exposes how speculation has gone far beyond the ability of the currently available evidence to yield answers. The author concludes that birds are best defined by a more traditional definition of the possession of feathers and avian flight architecture, that the so-called "feathered dinosaurs" are most likely derived avians, and that flight clearly originated from the trees-down, from ancestors that antedated the dinosaurs, rather than a direct linear descent"--
