恐竜説明:
This spectacular horned dinosaur stood 2 m tall. It was like a giant rhinoceros except that the bony frill at the back of the skull was adorned with six long spines. In addition it had a tall, straight nasal horn and two bony spikes just below and to the sides of the eyes. Together, these gave Shlracosaurus a lot of protection from attack by a giant predator. The tallest spines grew on either side of a central dip in the frill and they would have made even giants the size of Albertosaurus or T. rex thinks twice about attacking them. Styracosaurus lived in the western area of North America, including Montana, and in Alberta, Canada.
From the various skeletons discovered in Alberta, scientists have suggested that the heads of juveniles were very similar to those of adults although the spines and horns got larger as they got older. It was the biggest males that had the most spectacular head shields.
