One completely unexplored area in terms of physiology is the era of dinosaurs—with good reason, they lived over 100 million years ago and we’re left to make inference based on fossilized bones. However, by merging classical, comparative, and extreme physiology and applying it to current paleontological knowledge of dinosaurs, Balancing a Sauropod: The Physiology of a Dinosaur will for the first time begin to provide a sound physiological underpinning for how they may have lived 100 million years ago. Sauropods were the largest land animals to ever walk the earth with an incredible distance from heart to brain, begging the question, how did they maintain blood flow in their brain? Also, the climate sauropods lived in was hypoxic compared to what we live in now, so how did the dinosaurs breathe in the hypoxic Jurassic era? These questions and others expand to multiple fascinating questions the book will dissect in order of organ systems. The topics focus on major organ systems and apply them to potential sauropod physiology. Less emphasis is given to the skeletal system, as that has been discussed extensively in other literature. Each organ system will be discussed in terms of function and current understanding of how they work in a comparative environment. Balancing a Sauropod: The Physiology of a Dinosaur is written at a technical level to both inform the lay reader and provide a sound argument to scientists in the field.
