[30], Paleontologists Gregory Paul and Per Christiansen proposed that large ceratopsians such as Styracosaurus were able to run faster than an elephant, based on possible ceratopsian trackways which did not exhibit signs of sprawling forelimbs. Other members of the clade include Centrosaurus (from which the group takes its name),[16][17] Pachyrhinosaurus,[16][18] Avaceratops,[16] Einiosaurus,[18][19] Albertaceratops,[19] Achelousaurus,[18] Brachyceratops,[6] and Monoclonius,[16] although these last two are dubious. Styracosaurus (/stɪˌrækəˈsɔːrəs/ sti-RAK-ə-SOR-əs; meaning "spiked lizard" from the Ancient Greek styrax/στύραξ "spike at the butt-end of a spear-shaft" and sauros/σαῦρος "lizard")[1] is a genus of herbivorous ceratopsian dinosaur from the Cretaceous Period (Campanian stage), about 75.5 to 75 million years ago.

One species, S. albertensis, is currently assigned to Styracosaurus. What exactly did these carnivorous cultures eat, and how healthy or unhealthy were they? Each of the four longest frill spines was comparable in length to the nose horn, at 50 to 55 centimeters (20 to 22 inches) long.

It was an herbivore that had a frill that emanating from the back of its skull.
