Vertigo

I remember seeing something like this in a small Dino book that I still own. However, this is much more detailed and not as dark as the one I remember. I'm not sure how people can feel about extinct animals but I feel REALLY sorry for the loser Pachycephalosaurus since there is no way he's coming back for another bout. This, in a way shows how hard life is for males as not all of them will get their chance with the females.It kind of makes me appreciate that I am human and I won't have to butt heads risking my life to get a girl. Although I do have to commend the bone-headed dinosaurs as their head-butting sessions would have been quite a display.
