The Kentrosaurus was an omnivore and although the majority of dinosaurs were exclusively herbivore`s and carnivore`s, there were also omnivore dinosaur`s. Omnivore`s are animal`s that eat both meat and plant`s. Among all the dinosaurs, the stegosaurus had one of the lowest level`s of intelligence, and the Kentrosaurus was no exception: It`s small head held a brain about the size of a walnut. They had a really good sense of smell though which helped them out a lot. The Kentrosaurus is my favorite omnivore. Check out this video of a stegosaurus being threatened by an Allosaurus.
This is my drawing of a Kentrosaurus.
