Stop confusing Junior. There is no Sinosauroptyrex.
Too late. I'm extremely confused.
There is no Sinosauroptyrex.
At least not in the official literature. However, your chart earlier spells it exactly the same way as pby, which really makes me confused. One would think there would be lots of literature available on just about any dinosaur, let alone one as somewhat controversial as this one.
I'm beginning to think I've slipped into an alternate universe... again.
