This book depicts dinosaurs and other prehistoric animals living in this primitive land with 232 large high-definition hand-painted pictures, describes the appearance characteristics and life scenes of these prehistoric behemoths from the perspectives of morphology, habitat, hunting and evolution, and visually presents the distribution positions of dinosaurs and other prehistoric animals through topographic sketches. "Huge", "scary", "deadly" and "fierce" are the words people use to describe this ancient animal, but in fact it is difficult to label every animal as "fierce". Although Raptors have notorious deadly toes and claws, Tyrannosaurus Rex is one of the largest carnivores on land, but there are also herbivores like Brachiosaurus. As for dinosaurs, we can only guess their true appearance and complex lifestyle through scattered fragments and broken bones.
