A title in the "Exploring Dinosaurs" series, this volume introduces young readers to one of the earliest dinosaurs to walk the Earth, the Coelophysis, who lived in the Triassic Period, about 225 million to 208 million years ago. Because of its hollow, lightweight bones, this ancient reptile's name comes from the Greek words "hollow form." Although slender and small, about 10 feet long and weighing between 40 to 70 pounds, the Coelophysis was a swift, meat-eating predator that probably hunted in a pack. It also had the advantage of having an uncommonly large brain! The mystery of why this animal became extinct has fascinated paleontologists since its fossilized bones were first found in the late 19th century, and its life story will fascinate young readers. The sturdy hardcover volume also features a glossary of scientific terms used in the text, an annotated listing of books, websites and museums where more information about Coelophysis can be found, a subject index and a geologic timeline, describing the climate, vegetation and animals that lived during the major prehistoric eras. Illustrated throughout with scientific drawings, historic photos, color photos of fossils and dig sites, as well as imaginative paintings that help us picture what Coelophysisand its Triassic worldlooked like. 2004, The Child's World, Ages 6 to 10.
Gr 3-5-Each of these books opens with a dramatic scene to introduce the behavior and habitat of a dinosaur species. Subsequent chapters describe physical characteristics, diet, and other key data. Short, lucid sentences and double-spaced text keep the information easy to follow. Gray relates how scientists discovered and subsequently studied each species over time, conveying the importance of that work to our knowledge of dinosaur history and behavior. She also notes how theories and ideas can change with new discoveries. Special sections, set off with different backgrounds and smaller print, present slightly more complex information about topics such as fossil formation and dinosaur coloring, or about more specific events, such as the inaccurate naming of Oviraptor. These asides help keep the presentation lively and relate effectively to the main topics. Illustrations include various drawings of dinosaurs and photos of fossils and of paleontologists in the field. With the exception of Coelophysis, other recent titles on these species are available, but these volumes are well organized and offer the right amount of detail for their intended audience.-Steven Engelfried, Beaverton City Library, OR Copyright 2004 Reed Business Information.
