This dinosaur, Styracosaurus, was a relatively large dinosaur, reaching lengths of 18 ft and weighing nearly 3 tons. It stood about 6 ft tall. Styracosaurus possessed four short legs and a bulky body. Due to the fact the dinosaur was a herbivore, Lyra would be safe, although this particular beast most likely would knock over her carriage to see if it held any tasty vegetables or leaves.
