VERDICT This provides a compelling and visually stunning overview of the prehistoric past.--Jenna LaBollita

Good pictures and a basic education. Barrett, a merit researcher at the Natural History Museum, London, delivers an informative account of dinosaur evolution, emphasizing the Mesozoic era (from about 250 million to 66 million years ago), when dinosaurs dominated land and air with a nod toward an earlier era when their ancestor, a small lizardlike creature scuttled through the underbrush about 320 million years ago. As many readers know, a major extinction event occurred when a small asteroid struck the Earth, exterminating every traditional dinosaur but not birds, which were suspected to be related since Darwin's time but during the past 50 years have been accepted as genuine dinosaurs. Dinosaurs are reptiles that evolved one startling innovation: walking on two legs. All other reptile groups use four or none at all, and humans are among the incredibly few other mammals who became bipedal. The first dinosaurs were lightly built small bipeds with slender necks and long tails that expanded into varieties that dominated life on land for over 150 million years. Many grew to sizes that required more support, so they re-evolved four walking legs. Perhaps the most pleasure readers will experience in these books is poring over dozens of colorful artistic recreations of Mesozoic life, with crowds of dinosaurs going about their business in an authentic, if overcrowded, landscape. Because Barrett's emphasis is on fossils, there are plenty of those too. The complete specimens (rare in nature) are spectacular, but others appear to be clumps of bone, teeth, and rock, which reveal the reality of the puzzles that paleontologists encounter but deliver little information to the average reader. Steve Brusatte'sThe Rise and Fall of the Dinosaurs may be the best popular introduction, but this is an intelligent overview. Vivid insights for the dinosaur buff.
