Second perhaps only to Triceratops as the most well-known Ceratopsian, Styracosaurus lacked the eyebrow horns of its cousin, but more than made up for it with 4-6 long spikes on its neck frill, and a nose horn that could measure up to two feet long!
Styracosaurus could grow almost 20 feet long and weight over6500 lbs. It lived around 75 million years ago in the LateCretaceous Period, in what is now Alberta, Canada. It was found inthe Dinosaur Park Formation.
Styracosaurus was discovered in 1913 by C. M. Sternberg andnamed by Lawrence Lambe. The name Styracosaurus comes from theAncient Greek "styrax" which refers to a spike at the end of aspear shaft.
The purpose of Styracosaurus's large spikes and frill remain thesubject of much debate among scientists. Many theories have beenproposed, such as that the frill and horns were used in defenseagainst predators (including the Tyrannosaurus relativesGorgosaurus and Daspletosaurus), or that they served to impresspotential mates (and thus may have been brightly colored), and thatthey helped regulate the dinosaur's body temperature.
