Dinosaurs lived on Earth millions of years ago, long before our ancestors emerged on the face of the planet. These amazing animals boggle our imagination by their variety and size. Some were small like modern lizards, others as huge as a multi-storey building. Some were predators, for example the Tyrannosaurus Rex, Allosaurus, Velociraptor, Spinosaurus, while others were herbivorous - like the Diplodocus, Ankylosaurus and Iguanodon. Some species could fly, some lived in water, but most of them walked on the ancient land. Dinosaurs lived in the Mesozoic era, which is subdivided into three periods: Triassic, Jurassic and Cretaceous. Today, archaeologists study the remains of these animals and can only assume how they looked and lived.

Boys and girls of all ages love to color. The simple coloring mode is suitable for the smallest of children, including those of kindergarten and preschool age. These include simple and recognizable images that are easy to color. If the child selects the wrong shape, then they will be prompted with the correct number.
