Styracosaurus albertensis
Styracosaurus (meaning "spiked lizard" from the Ancient Greek styrax/στύραξ "spike at the butt-end of a spear-shaft" and sauros/σαῦρος "lizard") is a genus of herbivorous ceratopsian dinosaur from the Cretaceous Period (Campanian stage), about 75.5 to 75 million years ago. It had four to six long parietal spikes extending from its neck frill, a smaller jugal horn on each of its cheeks, and a single horn protruding from its nose, which may have been up to 60 centimetres (2.0 feet) long and 15 centimetres (5.9 inches) wide. The function or functions of the horns and frills have been debated for many years. Styracosaurus was a relatively large dinosaur, reaching lengths of 5.5 metres (18 feet) and weighing nearly 3 tonnes. It stood about 1.8 meters (5.9 feet) tall. Styracosaurus possessed four short legs and a bulky body. Its tail was rather short. The skull had a beak and shearing cheek teeth arranged in continuous dental batteries, suggesting that the animal sliced up plants. Like other ceratopsians, this dinosaur may have been a herd animal, travelling in large groups, as suggested by bonebeds.
Tuojiangosaurus multispinus
Tuojiangosaurus is a genus of stegosaurid dinosaur from the Late Jurassic Period, recovered from the Upper Shaximiao Formation of what is now Sichuan Province in China. Physically similar to the North American Stegosaurus, Tuojiangosaurus is the best understood of the Chinese stegosaurids. It was around 7 metres (23 ft) long and 2 metres (6.6 ft) high, with a postulated weight of around 4 tonnes (4.4 short tons). The type and only species, T. multispinus, was named in 1977 (exactly a hundred years after Stegosaurus) on the strength of two specimens, one over half complete. Like Kentrosaurus, Tuojiangosaurus had two rows of pointed plates along the spine, which became taller over the hip region. It also had two outward-pointing spikes on each side of the end of the tail, angled at approximately 45 degrees to the vertical. In stegosaurids, this spike arrangement has become affectionately known as the "thagomizer". It also had the typical narrow head, bulky body, and low teeth of other stegosaurids. Because it lacked the tall spines for muscle attachment found on the vertebrae of Stegosaurus, it was probably unable to rear up on its hind legs like that animal. This suggests that it would have eaten low-lying, ground vegetation.
