This guy is very bad. Maybe you're a dinosaur connoisseur, and you know it's a herbivore, and so you think it might react at best if you attack it. It is not so. This thing is not just territorial, it is evil itself. He will chase you, to your house, he will try to kill your prehistoric friends and if you are inside the house he will destroy it just to get you. Believe me, if you meet him, you either kill him or get killed. Escaping is possible, but it is always a risk. Don't go to your house for ANY REASON after meeting him. Wait a while somewhere else and if you are sure you have sown it go home.
