When fossils of birds from China's Jehol region first appeared in scientific circles, the world took notice. These Mesozoic masterpieces are between 120 and 131 million years old and reveal incredible details that capture the diversity of ancient bird life. Paleontologists all over the world began to collaborate with Chinese colleagues as new and wondrous fossil-related discoveries became regular events. The pages of National Geographic and major scientific journals described the intricate views of feathers as well as food still visible in the guts of these ancient birds. Now, for the first time, a sweeping collection of the most interesting of Jehol's avian fossils is on display in this beautiful book. Birds of Stone makes visible the unexpected avian diversity that blanketed the earth just a short time (geologically speaking) after a dinosaur lineage gave rise to the first birds. Our visual journey through these fossils is guided by Luis M. Chiappe, a world expert on early birds, and Meng Qingjin, a leading figure in China's natural history museum community. Together, they help us understand the "meaning" of each fossil by providing straightforward narratives that accompany the full-page photographs of the Jehol discoveries. Anyone interested in the history of life-from paleontologists to inquisitive birders-will find Birds of Stone an irresistible feast for the eyes and mind.

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.
