If I were, at about age twenty as a budding paleozoologist and paleoartist, handed a copy of this book by a mysterious time traveler, I would have been shocked as well as delighted. The pages would reveal a world of new flesh- and, in some cases, plant-eating dinosaurs and ideas that I barely had a hint of or had no idea existed at all. My head would spin at the revelation of the therizinosaurs, such as the wacky feathered Beipiaosaurus, and at the biplane flying dromaeosaurs, not to mention the little halszkaraptors with their duck-like beaks, the brow horns and atrophied arms of bulldog-faced Carnotaurus, or the bat-like membranous wings of scansoriopterygids.

The pages would have revealed a world of new sauropod and related dinosaurs and ideas that I barely had a hint of or had no idea existed at all. My head would have spun at the revelation of the neck spines of Amargasaurus and of sauropods so colossal that they not only gave the giant baleen whales a run for their money in terms of sheer  bulk but could feed over six stories high in tree crowns—and took only a few decades to get to those sizes!

This book got its start about seven years ago when Robert Bakker-the progressive dinosaurologist I studied with for many years-suggested that I draw up illustrations of some predatory dinosaur skeletons. About the same time, I started looking into the problem of bird origins, which I believed was tied to dinosaurs. One thing led to another and after a while I realized I had enough material available to put together a book on the dinosaurian meat eaters.

Having grown up reading that birds were at most only distantly related to dinosaurs, I was both startled and fascinated when a growing number of researchers began to argue that birds were the direct descendants of the terrible lizards. At the end of the 1970s, I was becoming involved in the ar¬ gument both as an artist and a scientist. Art and science could not be separated; the science deter¬ mined whether I should adorn the small predatory dinosaurs with scales or with feathers. Alas, there was no simple answer at the time, because there was no fossil evidence for either possibility. What I found disturbing was that many paleontologists were totally biased against illustrating dinosaurs with feathers, even though the available data was neutral on the subject. This bias only boosted my interest in researching bird origins. <...>

Pterosaur remains have been found by humans for millennia and may have helped form the basis for belief in mythical beasts, including winged dragons. In the prescientific West, the claim in the Genesis creation story that the planet and all life were formed just two or three thousand years before the great Egyptian pyramids were built hindered the scientific study of fossils. The discovery and subsequent detailed illustration of the virtually complete and articulated skull and skeleton of the small Pterodactylus found in fine-grained Lagerstätte sediments of Bavaria in the late 1700s began modern pterosaur paleozoology decades before the discovery of teeth and a few bones led to the recognition of land-bound dinosaurs in the 1820s. The strange pterodactyl skeleton posed a major problem for early science because it was still thought that major extinctions had not occurred. The creature had a hyperelongated single finger, which was radically different from the feathery airfoils of birds and also uite distinctive from the multifingered wings of bats. Nor did the very long, spike-toothed jaws belong to either group. <...>

The remains of ancient sea reptiles have been found by humans for millennia and may have helped form the basis for belief in mythical beasts, including dragons and sea serpents. In the prescientific West the claim in the Genesis creation story that the planet and all life were formed just two or three thousand years before the great Egyptian pyramids were built hindered the scientific study of fossils.
