Stegosaurus ungulatus

Stegosaurus ungulatus was a Late Jurassic herbivore.

Biology
Stegosaurus ungulatus lived in the forests and grasslands of Camo Bluff Wyoming. Stegosaurus is famous for the large plates on it's back and four thagomizers. Stegosaurus ate low lying plants of forests and grasslands. The Stegosaurus has recently been found to have a longer neck than previously thought. The scales of Stegosaurus were likely small, hexagonal, non-overlapping covex scales. Individuals probably had plates that differed in appearence, as a way to tell the difference between individuals, like the stripes of a tiger or zebra.

Stegosaurus was hunted by Allosaurus, with injuries from a thagomizer on an Allosaurus, and Allosaurus bite marks on a Stegosaur's plates. Cerartosaurus and Torvosaurus both probably hunted this animal. Stegosaurus one of the smallest brains in a dinosaur, with a brain only the size of two walnut. Stegosaurus seemed to of had a symbiotic relationship with the iguanodont Camptosaurus. The Camptosaurus had better eyesight and kept a lookout, while the Stegosaurus acted as a guard.

History
An escaped juvenile Allosaurus, in it's panicked state, attempted to attack a female Stegosaurus, and the Allosaurus was struck by the Stegosaur's thagomizer. Both were tranqed before any further damage could be done and the Allosaurus made a full recovery.
