What creature has been mistaken for a whale, a crocodile, and a sea dragon? How did a land lizard manage to become the greatest predator of the oceans? Why did its discovery turn 18th-century science upside down? What do their fossils tell us about evolution, extinction, and climate change? Could their relatives still be among us, camouflaged as modern snakes or lizards?

Mosasaurus, those colossal marine reptiles that dominated the seas over 66 million years ago, continue to ignite passion, questions, and awe. This is the story of their reign and their legacy.

In this book, renowned science communicator Pablo Marcos Rodríguez takes us on a fascinating journey through the rise and fall of these formidable predators. From their humble terrestrial origins to their complete conquest of the aquatic environment, History of Mosasaurs reveals how these astonishing reptiles lived, hunted, evolved, and vanished. As distant relatives of modern monitor lizards and snakes, their story unfolds through fossils, Cretaceous maps, and anatomical comparisons, immersing the reader in a vibrant marine world teeming with giant sharks, predatory fish, and creatures that seem to have sprung from mythology.

This work traces the history of mosasaurs while uncovering how the foundations of paleontology and evolutionary ideas were forged. A book that will captivate those drawn to prehistoric giants, to mysteries buried in time, and to discovering the testimonies of the past hidden within the rock.
