I'd probably say that my favourite dinosaur is the velociraptor. Small, fast, near impossible for its prey to escape.

I used to like the Triceratops since it could often defeat Tyrannosaurs and they were only attacked when those big carnivores were really hungry.
Yet somewhere I recently read that those long horns they had were no weapons instead they were used to attract mates, in this case Triceratops would not be all that cool anymore.
BTW many Anklyosaurus skeletons have been found laying upside down, which suggests that bigger dinosaurs could sometimes turn them over and eat them then when they were pretty much defenseless.

Yes, Victorian era paleoarcheologists made a whole lot of assumptions that have been dismissed after careful examination. I believe the story on Tyrannosaurus is that the teeth are the wrong shape for a big game hunter. Any twisting action of the T's head or the live, large prey would tend to break the teeth. Or something like that. |
I also heard it had to do with the way they know believe his bone structure went and that to have chased down animals at high speeds would have expended so much energy that it would not have been worth it. But I might be wrong with that.

From The Dinosaur Society Dinosaur Encyclopedia (Don Lessem and Donald F. Glut, Random House 1993):
Saichania
Type Species: chulsanensis
Order: Ornithischia
Suborder: Ankylosauria
Family: Ankylosauridae
Name: Mongolian saichan = beautiful
Size: 7 meters (24 feet) long
Period: Late Cretaceous, 79 million to 75 million years ago
Region: Mongolia
Diet: Herbivorous
"Saichania was an ankylosaurid, an armored dinosaur with small spikes on its flanks and a clubbed tail. It was unique among armored dinosaurs in that both its back and its belly armor were discovered. Others may have had such extensive protection, but their armor was not preserved.
"Saichania and Pinacosaurus differed from most of the other known Mongolian ankylosaurs in the structure of their nostrils and nasal cavities. The nasal cavity was divided into left and right passages. Within these passages were thin, spiralling bones. In living mammals, similar bones are covered with membranes that warm, moisten, and filter the incoming air. Similar nasal bones were recently discovered in Nanotyrannus, a newly named tyrannosaurid.
"If Saichania had a keenly developed sense of smell, it could have compensated for its slowness by warning it of approaching predators, and by helping it locate food sources in the semi-arid environment of the ancient Gobi."
