The painted picture shows an ancient sea predator Pleuracant, which existed about 370 million years ago. It has a streamlined body shape, a large head with sharp teeth and long fins, which allows it to maneuver perfectly in the water. Around Pleuranacanth are depicted other sea creatures, such as ammonites, which add context to its habitat in ancient times. This coloring book is suitable for children interested in paleontology and dinosaurs, as well as for those who want to show their creativity by adding bright colors to this ancient creature.
