STYRACOSAURUS (sty-RAK-o-sawr-us) "Spiked Lizard" (Greek styrax = spike + sauros = lizard, referring to the spikes on its FRILL)

A short-frilled CERATOPSIAN with six long spikes along the edge of its frill. A straight HORN nearly 2 feet (61 cm) long and 6 inches (15 cm) thick grew on its nose, but only stumps grew above its eyes. Like all ceratopsians, it was a four-legged plant eater with a bulky body and a relatively short, thick TAIL. Styracosaurus was 18 feet (5.5 m) long and 6 feet (1.8 m) tall. It probably weighed 3 tons (2.7 metric tons) Some scientists believe it was a good runner--it may have been capable of going 20 miles (32 km) per hour. Styracosaurus is known from a herd of 100 individuals and at least one complete skeleton found in Late Cretaceous deposits in Alberta, Canada.
