Re: another dumb question: Terror Birds are not dinosaurs?

Thank you all for your generosity in indulging this lay(wo)man's curiosity. Well, it leaves me wondering, more specifically, -- let say you were to find a fossil of T. Walleris and for some reason you had no way to know whether it were 2 million years old, or 70 million years old, and there were no trace of feathers, what would tip you off that this thing was closer to a chicken than to an oviraptor? The shortness of the tail?

neoavian neognath, but then you've lost the lay audience....)
