Synopsis

How can paleontologists know what a living dinosaur was like more than a hundred million years ago, particularly when only partial skeletons remain? Focusing on one large carnivorous dinosaur, Acrocanthosaurus ("high-spined lizard"), paleontologist Kenneth Carpenter explains the process, pairing scholarly findings with more than 75 color illustrations to reconstruct "Acro" before readers' eyes. In Acrocanthosaurus Inside and Out, he offers the most complete portrait possible of this fascinating dinosaur's appearance, biology, and behavior.

Acrocanthosaurus--similar in size to its later cousin Tyrannosaurus rex, but studded with large spines--roamed what is now the south-central United States 110 to 115 million years ago, during the Early Cretaceous. Carpenter worked on the most complete of the Acrocanthosaurus skeletons (nicknamed "Fran") that has been found. Here he describes the techniques that tell us about Acro's biological makeup, movements, and habits. Studies of joints reveal the range of possible motion, while bumps, ridges, and scars on the bones show where muscles, ligaments, and tendons attached. CT scans allow us to peer into the braincase, while microscopes afford a cross-sectional view of bones. These findings in turn offer an idea of how Acro stalked and ate its prey.

Scientific evidence beyond the fossils provides avenues for further inquiry: What does the sedimentary rock encasing Fran's bones tell us about Acro's environment? What does our knowledge of Acro's distant relatives, such as crocodilians and birds, imply about its heart and other soft tissues? Can our understanding of other animals explain Acro's huge spines?

Carpenter distills all this information into a clear, accessible, engaging account that will appeal to general readers and scholars alike. As the first book-length work on Acrocanthosaurus, this volume introduces a prehistoric giant that once stalked Texas and Oklahoma and offers a rare, firsthand glimpse into the trials and triumphs of paleontology.
