Saurischians
The definition of a Saurischian dinosaur is, that the Saurischian had unlike the Ornithischian a lizard-hipped bone structure, which is pointing down and forwards, later the Saurischians got a hip like a bird. In the group of the Saurischians, there were both herbivorous and carnivorous representatives, it means that there was an extreme difference between the individual dinosaur in this group. In the first suborder of the Saurischians there are the terrible, flesh eating Theropods, such as the Tyrannosaurus and the Allosaurus, but in the other suborder there are the giant, plant eating Sauropods, such as the Brachiosaurus and the Diplodocus.
