This book will tell you absolutely everything about one of the most recognizable ancient lizards — stegosaurus! What were the dorsal plates with which it was covered for? Is it true that the teeth of this dinosaur were not adapted to chewing and he had to swallow stones to grind food right in the stomach? All this and much more will be told to the guys by the British scientist and traveler Ben Garrod, nicknamed "Doctor Bone"! You won't have to get bored with him: instead of the standard enumeration of encyclopedic facts, readers are waiting for comics with reconstructions of the battles of primitive lizards, instead of long—known information - amazing discoveries of 2017 and 2018. And at the end of the book there is a workshop of a young paleontologist, telling about the features of the study of those types of fossils that cannot be extracted from the ground. The publication is intended for children of secondary school age.
