Avimimus
Avimimus was an omnivorous dinosaur that lived in Mongolia during
the late
Cretaceous period,
about 70 million years ago.
Avimimus was about 5 feet (1.5 meters) long. Although it had a relatively small
head (compared to its body), it does seem to have had a relatively large brain
and eyes. It was equipped with a serated beak, and this is usually though to
suggest that the animal was a herbivore (eating only plants) or omnivore (eating
both plants and meat), although there is an alternative hypothesis that it was
an insectivore (specialized in eating insects).
The bones of the animal's hand were fused together like in modern birds, and
most paleontologists believe that Avimimus was covered in feathers (there are indications
of the attachment points for feathers on arms).
It has been suggested that perhaps Avimimus might have been capable of weak flight, but
many, perhaps even most, paleontologists think that the Avimimus probably could not fly,
but instead was specialized in running - evidence for this is provided by the bones of
its legs, which seem to be those of a running animal.
Avimimus was an omnivore (ate meat and plants) that lived about 70 million years ago

Scientists have recovered more than a billion fossils, but no discovery has been more breath-taking than the fossils recently found in northern China, findings which prove that several families of dinosaurs had feathers, or feathery hair-like coverings, adorning their bodies.
Now in the beautifully designed Feathered Dinosaurs, paleontologist John Long and illustrator Peter Schouten provide a stunning visual record of these extraordinary prehistoric creatures, illuminating the evolutionary march from primitive, feathered dinosaurs through to the first true flying birds. Schouten, an acclaimed natural history artist, has created 80 full-color paintings that capture the striking physical traits of these feathered dinosaurs. Drawing on his extensive knowledge of the lifestyles of modern birds and mammals, plus the extant scientific data regarding how these dinosaurs might have looked and behaved, Schouten has produced not only the most beautiful but also the most accurate visual representations of these animals in print. Equally important, John Long, a noted paleontologist and widely published science author (with some 24 books to his credit), provides an engaging companion text that places these feathered dinosaurs within the larger family of dinosaurs--for instance, outlining their relationship to T. Rex and Velociraptor, species well known to Jurassic Park fans--and discusses the factual information that can be deduced from their fossil remains, in effect providing an insightful natural history of this remarkable group.
A true marriage of art and science, Feathered Dinosaurs presents an unprecedented visual record of one of the most significant breakthroughs in the history of vertebrate paleontology--the discovery that many predatory dinosaurs were cloaked with feathers, perhaps just as colorful and fanciful as those of their living relatives. |

"I'm sure that May 21, 1986, will remain among the most memorable days of my career. On my way to Albuquerque, New Mexico, I had stopped in Lubbock, Texas, to study the Triassic archosaurs collected by Sankar Chatterjee from the Dockum beds of west Texas. I expected to see fossils of the large-headed carnivore Postosuchus, the armored herbivore Desmatosuchus, and the crocodile-like parasuchians. I wasn't expecting to see what I saw..." -- Lawrence M. Witmer, from the foreword Dinosaurs are so popular that we often neglect their flying relatives that are still among us. Birds, the true "living dinosaurs," deserve considerable respect as successful vertebrates that have evolved, adapted, and survived over a period of 225 million years. The Rise of Birds is the first detailed, illustrated, and comprehensive review of the fossil record of birds in a modern phylogenetic context. Distinguished paleontologist Sankar Chatterjee provides a clear and exciting chronology documenting the long odyssey of birds since Protoavis -- which may have taken to the air some 75 million years before the widely known "first bird," Archaeopterix. Throughout The Rise of Birds, Chatterjee offers a wealth of fascinating details from the colorful history of birds past and present. Among them: • Some intelligent theropods such as dromaeosaurs were arboreal and could climb trees with their swivel wrist joint and stiff tail. They were capable of parachuting and gliding from tree to ground. • The discovery of downy theropod dinosaurs from China indicates that upper jaw mobility, not feathers, is the most distinctive characteristic of birds. • Most birds were wiped out 65 million years ago, along with the dinosaurs, by large meteoritic impacts. However, few lineages of birds rebounded from this catastrophe and underwent an explosive evolution. The Rise of Birds discusses the significance of all the many recently discovered bird and possible bird fossils, from Europe to China to Latin America. Chatterjee outlines the varying theories of how animal flight developed, and he explains, in terms of comparative anatomy, what makes a bird a bird. The book covers some of the greatest events in avian development: their emergence in the Triassic pangean world, their flight refinement and global diversification during the continental breakup of the Jurassic and Cretaceous periods, their sudden decline at the end-Cretaceous extinction, their rebound and explosive radiation dur-ing the Cenozoic era, and finally their destiny with us. Beautifully illustrated by Michael W. Nickell, this book will be of interest to a broad range of readers, including vertebrate paleontologists, ornithologists, and amateur naturalists, including birders. |

Our knowledge of the origin and early evolution of birds has exploded in the past ten to fifteen years. In the 1990s alone, scientists became aware of approximately three times more species of early birds than were previously known, marking the first 85 million years of avian development as a period of remarkable species diversity. Assembling work by an international group of renowned scientists, Mesozoic Birds: Above the Heads of Dinosaurs is the most authoritative and up-to-date source on early avian evolution currently available. This unique resource provides a comprehensive examination of the known fossil record and is also an unparalleled guide to the fast-paced developments in current research.
Mesozoic Birds: Above the Heads of Dinosaurs covers a wide range of topics, including discussions of avian origins, the fossil record of feathers and footprints, bone histology, and locomotor evolution. Controversial taxa such as Protoavis, Caudipteryx, and Mononykus receive special treatment. But the heart of the volume presents the anatomy, relationships, and paleobiology of the undisputed Mesozoic aviary. Some of the book's most exciting features are the new definitive descriptions and illustrations of taxa that previously have received only brief notice, such as the alvarezsaurid Shuvuuia; the enantiornithines Sinornis; Eoalulavis, Vorona, and Patagopteryx; and the hesperornithiform Enaliornis.
The origin of birds and their relationship to dinosaurs continue to be hotly debated among paleontologists, ornithologists, and evolutionary biologists. This cutting-edge reference will become an essential resource for those interested in this debate and in the many other fascinating topics relating to the evolution of the earliest known birds. |
