Kurzbeschreibung des Verlags

For more than sixty-six million years, the living warmth of Tyrannosaurus rex seemed permanently lost. Its bones could reveal its enormous size. Its teeth could testify to a devastating bite. Fossil footprints could preserve moments of movement. Yet one deeply personal detail about this legendary predator remained hidden: what was happening inside its body while it was alive?Then scientists learned how to read a chemical message preserved inside fossil tooth enamel. From only a tiny amount of ancient material came an extraordinary estimate: T. rex maintained a body temperature near 97 degrees Fahrenheit. That number opens a new window into the animal's metabolism, stamina, appetite, climate tolerance, and daily struggle for survival, bringing us closer to the breathing, moving creature behind the museum skeleton.Inside, you'll discover- How fossil tooth enamel can preserve biological information for tens of millions of years- Why carbon and oxygen isotopes can act like a prehistoric thermometer- What the 97-degree temperature estimate really means, including its scientific uncertainty- How the evidence reshapes the long debate over warm-blooded and cold-blooded dinosaurs- Why elevated metabolism may have influenced stamina, movement, hunting, and feeding demands- How T. rex compares with mammals, birds, reptiles, and ancient crocodilians- Why a warm body could help tyrannosaurs function in cooler and strongly seasonal environments- What fossil evidence reveals about predator behavior, growth, breathing, and energy use- How scientists distinguish direct evidence from reasonable interpretation and unanswered questions- Why fossil thermometry could transform what we learn from Triceratops, sauropods, ancient mammals, giant sharks, and other extinct animalsThis is not simply a story about whether T. rex was warm-blooded. It is about what happens when a familiar animal becomes unfamiliar again. Behind the massive jaws and frightening reputation was a living organism that needed oxygen, food, warmth, endurance, and enough energy to survive each day. Modern science is beginning to recover traces of that hidden biological life from places no one could once have imagined.T. Rex at 97 Degrees invites curious readers into the changing world of modern paleontology, where fossils are no longer viewed only as remnants of death. With chemistry, climate science, anatomy, and careful interpretation, they can become records of life itself, preserving faint but remarkable clues about how one of Earth's most famous predators actually functioned.
