Yet Another Stegosauropod

It's almost as if stegosaurs and sauropods had some kind of rivalry going on. First off, you've got Brachytrachelopan, a small Patagonian sauropod with a downturned, shortened neck. Those stegosaurs aren't the only low-grazers in town! A few years later, the stegosaurs up the ante: Miragaia, a curiously long-necked stegosaur who has more cervical vertebrae than any self-respecting sauropod. Take THAT, Sauropoda. Well, while I was in London, the sauropods shot back, with Spinophorosaurus, a normal-sized sauropod with a thagomizer. And this ain't no weaksauce club, Shunosaurus, it's a four-spiked, stegosaurian thagomizer. One wonders how the Stegosauria will respond next.
