Styracosaurus was a relatively large dinosaur, reaching lengths of 5–5.5 metres (16–18 ft) and weighing about 1.8–2.7 metric tons (2.0–3.0 short tons). It stood about 1.8 meters (5.9 feet) tall. Styracosaurus possessed four short legs and a bulky body. Its tail was rather short.
Ceratopsidae (sometimes spelled Ceratopidae) is a family of ceratopsian dinosaurs including Triceratops, Centrosaurus, and Styracosaurus. All known species were quadrupedal herbivores from the Upper Cretaceous .

A. sphenoceros was originally referred to the genus Monoclonius and later to Styracosaurus, while M. recurvicornis is a possibly a valid species but has yet to receive a new genus. The body was based on a more complete skeleton of the species Triceratops prorsus that had been described and

One exceptionally large specimen later became its own genus, Titanoceratops, due to its more derived morphology, similarities to Triceratops, and lack of unique characteristics shared with Pentaceratops. [2] [3] Pentaceratops was about 5.5–6 meters (18–20 ft) long, and has been estimated to have weighed around 2.5 metric tons (2.8 short tons).
Centrosaurus is found lower in the formation than Styracosaurus, indicating that Centrosaurus was displaced by Styracosaurus as the environment changed over time.
