Deborah Cadbury’s The Dinosaur Hunters (also known as Terrible Lizard): a review

Although this book isn’t about military history it is about one of my other passions.

Deborah Cadbury’s The Dinosaur Hunters (also known as Terrible Lizard) is a popular and engaging history of early paleontology that captivates readers with its vivid storytelling and well-researched details. It tells the true story of the fierce rivalry between two prominent 19th-century British scientists, Gideon Mantell and Richard Owen, whose contrasting personalities and ambitions ultimately led to the remarkable discovery of the world’s first dinosaurs. Mantell, a determined and often underestimated figure, was driven by a passion for fossils and a desire to make his mark in the scientific community, while Owen, a more established authority, sought recognition and prestige. Their interactions were marked by both collaboration and conflict, revealing not only the complexities of scientific discovery but also the deeply human emotions involved in the pursuit of knowledge. Cadbury should be commended for her ability to transform what could have been a dull academic history into an exciting narrative filled with drama, intrigue, and the personal struggles of these pioneering figures, making it a must-read for both science enthusiasts and general readers alike.

​The book’s central focus is the compelling conflict between its two main characters. Gideon Mantell, a passionate, self-taught country doctor, was the initial discoverer of the giant fossil bones, most notably those of the Iguanodon. His obsessive dedication to his work, often conducted at great personal expense, led him toward a tragic life marked by misfortune, including the loss of his family and a crippling injury. In stark contrast stands Richard Owen, a brilliant, well-connected anatomist who enjoyed the favor of the London scientific establishment. While Owen is credited with coining the term “Dinosauria” (meaning “terrible lizard”), Cadbury portrays him as a ruthless and calculating antagonist who actively sought to undermine Mantell’s career, appropriate his discoveries, and secure all the professional acclaim for himself. This high-stakes clash between the struggling provincial genius and the powerful, morally questionable insider forms the “heroes and villains” narrative that makes the book so gripping.

​Beyond the personal feud, Cadbury successfully frames the discoveries within the broader context of Victorian science and society. The narrative expertly details the emerging understanding of geology and stratigraphy—the science of rock layering—which provided the key to dating the fossils. It also explores the intense cultural and intellectual tension of the era, illustrating how the physical evidence of enormous, extinct reptiles directly challenged the prevailing literal interpretations of Biblical creation. Reviewers highlight that the book is not just about the dinosaurs themselves, but about the “human element in scientific discovery”: the sacrifices, the intense ambition, the ethical compromises, and the profound shift in understanding our planet’s history. Overall, The Dinosaur Hunters is highly recommended as a fast-paced, scholarly yet exhilarating introduction to the birth of a major science.

A great read.
