I love you, Spike

Stegosaurus Week (13th Sept to 19th Sept) is coming to a close, and I haven't made a single mention about the Stegosaurus.

For those who don't know, Stegosaurus was a herbivour which first appeared in the Jurassic (and probably had epic battles of survival against Allosaurus). The most commonly identified of the Stegosauridae family is most likely Stegosaurus stenops, since nearly everywhere I look (if you're searching for dinosaurs as much as I am), S. stenops is almost like the posterchild for what a Stegosaurus species is characterised for. It was short and stocky, but with large plates and typical 4 spikes on the end of the tail. Although, it wasn't the largest stegosaurid, it does seem to be the most common species.

So why is Stegosaurus so awesome??
Besides the clearly lethal set of tail-spikes Steg sported, and the pretty cool looking fashion statement they made during the Jurassic with their plate(-like Mohawks), there is one really awesome thing about Stegosaurus:

It had a "second brain"; near the base of its tail used for controlling reflexes in the rear part of its body. The "brain" in the hip region was not made of brain tissue, but instead, a complex nerve centre; the "sacral plexus." It was a secondary control center for the spinal cord. So despite the obvious tiny size of Stegosaurus' brain, and the possibility that it may have lacked intelligence, didn't mean it wasn't cleverly designed for its time in an evolutionary time-frame.
