Hesperosaurus was closely related to Stegosaurus. It had a low, rounded bone plate, smaller size and a broad skull. It has a small brain, which means it lacked an advanced mentality and was not a very active animal. Its skull was compared to its body. It evolved into a faster and more flexible dinosaur. It swung its tail wildly behind it to deal with flanking attackers that were declared as a defensive weapon. This creature had a four-pronged thagomizer on the end of its tail. It was a plant-eating animal, such as ferns, mosses, cycads, horsetails and conifers. It stood on all fours and reproduced by laying eggs.<\/p>\n\n\n\n

Hesperosaurus was a large stegosaurus that was estimated to be 6.5 meters long and weighed 3.5 tons.<\/p>\n\n\n\n
