Raptor hand signaling??

Exactly who came up with that idea? Supposedly it came from Walking With Dinosaurs, but I never saw all of it, so I don't remember this part.

While the idea doesn't sound too outrageous, I mean it is possible hand signaling did exist, but there's just no evidence for it. I don't think you can really tell too much specific behavior like that from a few bones.

Also I'd think body posture could play a part in communication also, the way tail is pointed, ect.

Yeah, I believe that body language is important in nearly every species, humans included.
