They don't look at all the same though? A triceratops looks more similar to a rhino than to a T-Rex. And neither of them look remotely like a brachiasaur.

  True, but they seem (again, to the untrained eye) less diverse than today's fauna. Untrained eye = know about dinosaurs from Jurassic Park. They did not seem to have evolved to use tools either, or some kind of burial process (though we do not probably know), or art-like creations (again, we probably do not know). What I meant with my comment is that we talk a lot about evolution and I find that dinosaurs spanning some 150 M years (vs 2 M for humans) are not used enough in presentations of evolution. It would probably be great to say: look, 150 M years of evolution changed this and that (say, minor changes) because of this and that (environment pressure, ...) as opposed to [something, humans for instance, or giraffes, or other examples usually used in such discussions] that only took X k/M years to go from A to B. I would find it a good message to convey, as everyone knows about dinosaurs but not that much about their time span.

That's mainly because we don't really know what they looked like apart from their general bone structure. Imagine we tried to reconstruct what modern mammals looked like from their bones so gave all of them short brownish fur.
