I certainly remember ol' Steggy; one of the most architypical dinosaurs around (like Triceratops, Tyrannosaurus, Iguanodont and the non-dinosaurs, Dimetrodon and Pterodactyl). But actually, what I was refering to was the Sauropods. I recall what you mean about Steggy, but the notion with the Suaropods was that their neck was so very long, and so far from the tail, that they were thought to have a relay station of sorts. (Such a "relay station" does, in fact, exist even in humans, but only in a much more simple form.)
By the way, speaking of ol' Steggy: Did they ever figure out how to attach the plates? Or what exactly they were for? Last I saw, they were still showing them as a frill down the spine, but were becming suspicious of that.
You're right. In males, we call it the "little head". It definitely thinks for itself and is quite capable of controlling our behaviour. /grin
