Millions of years ago, the oceans teemed with creatures that were every bit as fascinating and ferocious as the dinosaurs that ruled the land. These were the marine reptiles that seem completely alien to our modern eyes. These included the massive-jawed pliosaur, the super speedy Mosasaur, and the long-necked plesiosaur. This book covers a very long period, from 430 to just 1.6 million years ago, and not all these species existed at the same time yet many were the dominant predators of their era. This book explores how these awesome creatures lived, how they hunted, and how we know about them today
