Jurassic Park: 10 Deadliest Dinosaurs

8. Pachycephalosaurus

In Real Life: A species with sadly only a few full sets of remains discovered, the skeletal structure has led scientists to theorise that Pachycephalosaurus charged opponents and used the combination of a extraordinarily thick dome skull and spine alignment to incapacitate opponents by ramming them at high speed. Although boasting a brain size to put it in league with Stegosaurus, Pachycephalosaurus was certainly not without weapons. In The Films: While Pachycephalosaurus doesn€™t get as much attention as viewers might have liked in The Lost World, the species makes a heck of an impression as it very effectively demonstrates its hypothesised special skill and does some serious damage to InGen property by charging at anything - or anyone - with the misfortune to be in its way. MVP Moment: As the InGen invaders attempt the corral the dinosaurs on the game trail on Isla Sorna, Pachycephalosaurus puts up a fight and delivers a very high-velocity headbutt to a goon€™s chest, knocking him into and then through a car. Confirmed Kills: 0 - although the goon wasn€™t going to be getting up very quickly
