Peel back the layers, hear the sounds, and discover the dinosaurs that lie in wait! Using an innovative format, Layer by Layer: Discovering Dinosaurs presents young readers with six interactive scenes depicting prehistoric creatures in natural settings with atmospheric sound recordings. Each spread includes several layers for readers to peel back so they can follow the movements of the dinosaurs through the transforming scenes and answer questions about the animals' actions. Under the final layer of each scene, kids will be greeted by a surprise that concludes the narrative. The layered views provide an exciting sense of exploration for curious kids who are ready to uncover the fascinating beasts of the Mesozoic era.

Barnum Brown's (1873-1963) parents named him after the circus icon P.T. Barnum, hoping that he would do something extraordinary--and he did! As a paleonotologist for the American Museum of Natural History, he discovered the first documented skeleton of the Tyrannosaurus Rex, as well as most of the other dinosaurs on display there today. An appealing and fun picture book biography, with zany and stunning illustrations by Boris Kulikov, BARNUM'S BONES captures the spirit of this remarkable man. Barnum's Bones is one The Washington Post's Best Kids Books of 2012.

Explains the evolutionary relationship of dinosaurs, answers fifty specific questions about them, profiles forty-one specimens, and describes six expeditions of the American Museum of Natural History.

In 1878, the first complete dinosaur skeleton was discovered in a coal mine in Bernissart, Belgium. Iguanodon, first described by Gideon Mantell on the basis of fragments discovered in England in 1824, was initially reconstructed as an iguana-like reptile or a heavily built, horned quadruped. However, the Bernissart skeleton changed all that. The animal was displayed in an upright posture similar to a kangaroo, and later with its tail off the ground like the dinosaur we know of today. Focusing on the Bernissant discoveries, this book presents the latest research on Iguanodon and other denizens of the Cretaceous ecosystems of Europe, Asia, and Africa. Pascal Godefroit and contributors consider the Bernissart locality itself and the new research programs that are underway there. The book also presents a systematic revision of Iguanodon; new material from Spain, Romania, China, and Kazakhstan; studies of other Early Cretaceous terrestrial ecosystems; and examinations of Cretaceous vertebrate faunas.

Describes how the study of fossilized remains has given paleontologists information on the dinosaurs.

Uses hands-on activities to present information about dinosaurs and to show how paleontologists have learned about these prehistoric creatures.

Through photos and narrative, some of Texas' most dedicated scientists show you actual specimens of dinosaur material found in Texas, as well as dinosaur exhibits found throughout the state.

Examines the discovery of fossilized dinosaur eggs by a group of scientists in Argentina.

Sixty-five million years ago, a comet or asteroid larger than Mount Everest slammed into the Earth, inducing an explosion equivalent to the detonation of a hundred million hydrogen bombs. Vaporized detritus blasted through the atmosphere upon impact, falling back to Earth around the globe. Disastrous environmental consequences ensued: a giant tsunami, continent-scale wildfires, darkness, and cold, followed by sweltering greenhouse heat. When conditions returned to normal, half the plant and animal genera on Earth had perished. This horrific chain of events is now widely accepted as the solution to a great scientific mystery: what caused the extinction of the dinosaurs? Walter Alvarez, one of the Berkeley scientists who discovered evidence of the impact, tells the story behind the development of the initially controversial theory. It is a saga of high adventure in remote locations, of arduous data collection and intellectual struggle, of long periods of frustration ended by sudden breakthroughs, of friendships made and lost, and of the exhilaration of discovery that forever altered our understanding of Earth's geological history.
