Unlike Stegosaurus , it had a large spikes sticking out from its shoulder .

Troodon facts

This theropod had many unique features . Its Brain was one of the largest of any dinosaur , relative to its size , which means it was probably one of the smartest dinosaurs . It had stereoscopic vision so it had good depth perception and it had big eyes . Its teeth had large serrations-they resemble the teeth of some of the plant-eating prosauropods which could mean Troodon was one of the first dinosaurs to be named in the USA..

Torosaurus facts

Torosaurus had one of the longest skulls ever found ; it was 10 feet long. The Frill was more than half the length of the skull and had two large openings to make it lighter . Its skull and body were more lightly built than those of the massive triceratops , the most famous ceratopsian . Both dinosaurs lived to the end of the Cretaceous , but there were not so many "Torosaurus". For every one Torosaurus skull fond, 15 Triceratops skulls were found.

This ornithopod is most famous for being the prey of Deinonychus. At one site a body of  Deinonychus . At one site a body of "Tenontosaurus" was found with tow Deinonychus skeletons nearby. Scientists think Deinonychus killed and partially ate the plant eater and the two Deinonychus were then attracted to the free meal . After a fight over the body , the two Deinonychus were killed. The bones of Tenontosaurus showed tooth marks that look like Deinonychus teeth impression..

Stygimoloch was a dome-headed dinosaurs, Stygimoloch , Dracorex and Pachycephalosaurus may be different growth stages of the same species in which the bumps hooks and knobs on the skull were gradually replaced by a dome of solid bone.

Sinornithomimus facts

The description of "Sinorthimimus" is based on the study of nine skeletons of young dinosaurs found together-no adults were found . The nine dinosaurs were probably part of a family group that died at the same time . The adults must have either been away when the disaster hit or they escaped . Feathers were found with the skeletons as were stomach stones or gastroliths which tell us this dinosaur ate plants

"Segnosaurus facts"

Senosaurus had a long skull with small teeth, something like a Triassic Prosauuropod . Its hands had long claws and its foot had four toes not three as in most other theropods. These features would make sense of Segnosaurus hunted fish from the water-it probably did but we do not know this

Its back was covered with bony bumpsin the skin or ossicles .Some were flat and some were raised , like ridges they were spaced just far enough apart so that a theropod would break at least one tooth if it tried to bite Scutellosourus. This dinosaur walked on two legs unlike the other armored ornithischians

Scipionyx facts

This young theropod lived in Italy about 110 million years ago . It is one of the best-preserved dinosaurs ever found. This is because it was buried in limestone and in a low-oxygen environment , which prevented the decay that normally occurs during fossilization. The fossil was a rare find - it had preserve soft tissues including the gut liver and muscles

Its skull was thank its jaws were too weak for active hunting . It could have eaten the remains of other dead dinosaurs . Its upper jaw curved upward which probably made "Rugops" look like it was smiling . Rugoops live about 95 million years ago. The discovery of a Rugops skull in Niger Africa demonstrates that this landmass was still a part of the great southern continent Gondwana , at that stage in Earth's History.
