My first attempt at drawing an Einiosaurus in several years. This dinosaur lived in North America during the Cretaceous Period, around the same time as Daspletosaurus, the ancestor of Tyrannosaurus. Einiosaurus belonged to the Pachyrhinosaurus "tribe" of the Centrosaurus family. Compared to its much better-known relative, Triceratops, Einiosaurus was quite modest in size—4.5-6 meters long and weighing 1.3 tons
