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,
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.
