You must have missed the poster paper by T. R. Karbek, "The case for Stegosaurus as an agile, cursorial biped." -- Jeff Hecht

LOL ... nice to know that in an age of bitter controversy, dinosaur science can still take a breather and prove some pretty obvious facts. What's next, actual evidence that sauropod necks attached to the front of their torsos and not the middle of their backs? ;)
