Gigantspinosaurus (meaning giant-spined lizard) is a genus of dinosaur from the Late Jurassic. It was a stegosaur found in the Upper Shaximiao Formation of Zigong, Sichuan, China, and is known from a partial skeleton missing the skull (except for the lower jaw), hind feet, and tail. The most notable aspect of Gigantspinosaurus was its two shoulder spikes, twice the length of its shoulder blades and longer than any other spikes on its body. Paleontologists disagree about which way these blades faced, up and out or over and back, a matter that probably won't be settled until further fossil discoveries are made.
