Children's LiteratureA 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.
