To my knowledge all feathered dinosaurs are ceolosuarian, meaning that they are descendants of one small Triassic dinosaur. Ceolosuarian cover a large range of theropods that eat either meat or plants. We do known however that this does not cover all dinosaurs as all ceolosuarian are orithosrithian ( forgive my spelling) and there are still saurischians as well. As well we have carnosaurs which are a whole other lineage of animals.
You have it backwards. Birds and theropods are saurischians, not ornithischians, despite the name. Ornithischians have a hip structure superficially similar to birds, but they are otherwise much less similar to birds than saurischians.
I realized that after I read your post. Also you may find this interesting. http://en.m.wikipedia.org/wiki/Protoavis
I'm skeptical of this find but it does pique my interest.
To-morrow, and to-morrow, and to-morrow,
Creeps in this petty pace from day to day,
To the last syllable of recorded time;
And all our yesterdays have lighted fools
The way to dusty death. Out, out, brief candle!
Life's but a walking shadow, a poor player,
That struts and frets his hour upon the stage,
And then is heard no more. It is a tale
Told by an idiot, full of sound and fury,
Signifying nothing.
