Book Description
The Ceratosauria is modified to include two super families with one new subfamily. Two new species of Ceratosaurus are described, the first based on an articulated skeleton from the Fruita Paleontological Area in western Colorado, and the second on skeletal elements of a single individual from the Cleveland-Lloyd Dinosaur Quarry in east-central Utah. A number of additional specimens, identifiable only to genus, have been found in North America and are mentioned or briefly described. Specimens from East Africa and Switzerland are also considered to be identifiable only to genus. The peculiar genus Labrosaurus is placed in synonymy with Allosaurus.

Book Description
The famous bone beds of the Morrison Formation, formed one hundred and fifty million years ago and running from Wyoming down through the red rock region of the American Southwest, have yielded one of the most complete pictures of any ancient vertebrate ecosystem in the world. Jurassic West, Second Edition tells the story of the life of this ancient world as scientists have so far been able to reconstruct it. Aimed at the general reader, Jurassic West, Second Edition recounts the discovery of many important Late Jurassic dinosaurs such as Apatosaurus, Allosaurus, and Stegosaurus. But dinosaurs compose barely a third of the more than 90 types of vertebrates known from the formation, which include crocodiles and turtles, frogs and salamanders, dinosaurs and mammals, clams and snails, and ginkgoes, ferns, and conifers. Featuring nearly all new illustrations, the second edition of this classic work includes new taxa named since 2007, updates to the naming and classifications of some old taxa, and expanded sections on numerous aspects of Morrison Formation paleontology and geology.
