9. Stygimoloch
As well as the beasties that could rip you in two while you sit on the toilet, Jurassic Park has also given us a fairly wide variety of herbivorous dinosaurs. Pachycephalosaurids, the dinosaurs with the big, thick, domed skulls, made a brief appearance in sequel The Lost World, but not in this particular species. Stygimoloch is the most interesting looking of the Pachycephalosaurs. Its name roughly translates as "demon from the river of hell" (although geeky fans may prefer the related Dracorex hogwartsia, "dragon king of Hogwarts"). While a "veggiesaurus", Stygimoloch's skull, covered in spines and horns, gives it an impressively monstrous demonic look that would be fun to see as part of Jurassic World. Although we don't really know what these hard heads were for, the general feeling is that they were likely to be used for head-butting, ramming themselves together head on like goats today. Again, these are not necessarily dinosaurs that could provide a direct threat to our human heroes, although they would probably want to get out of the way of one when it was charging. This is more likely to be a creature that is met early on and impresses us and the characters with the recreated dinosaur world on offer, like the Stegosaurs in The Lost World.
