Styracosaurus is extremely social, and requires at least five or six individuals in its enclosure to be happy. Their favourite foliage is the ginko tree or other dinosaur based trees such as magnolia. Styracosaurus is a deciduous forest animal, but also likes patches of grass, dirt and sand, as well as a large body of freshwater for drinking. In Freeform mode, it is one of five prehistoric animals available for adoption at the start of the game. Styracosaurus is an adoptable animal in Zoo Tycoon and was added as part of the Dinosaur Digs expansion pack. Further evidence of this exists in the discovery of a bonebed in Arizona, USA with about 100 Styracosaurus fossils. Like other ceratopsians, this dinosaur was most likely a herd animal, traveling in large groups and caring for its young after they hatched. Its large beak and cheek teeth indicate that its diet was herbivorous and composed mostly of cycads, palms, and other prehistoric plants. Styracosaurus possessed four short legs and a bulky body, and was probably able to achieve speeds of up to 32 kilometers per hour (20 miles per hour). The first fossil remains of Styracosaurus were discovered in Alberta, Canada in 1913, in an area now known as the Dinosaur Provincial Park.

It was a large dinosaur, reaching lengths of 5 meters (18 feet) and weighing as much as 3 tons. It had six long horns extending from its neck frill, a smaller horn above each of its eyes, and a single horn protruding from its nose at 60 centimeters (2 feet) long and 15 centimeters (6 inches) wide. Styracosaurus is a member of the ceratopsid family of dinosaurs from the Cretaceous period.
