Species: J. shangyuanensis (type).
Type: Possibly omnivorous.

       The discovery of Jeholosaurus raised some eyebrows as even though it is an ornithiscian dinosaur with distinctively herbivorous teeth towards the back of its mouth, the frontal teeth look that those of a carnivore. This has brought forth the hypothesis that Jeholosaurus was an omnivore, either hunting smaller animals or scavenging carrion to supplement its diet of plants. The only other possibility is that Jeholosaurus specialised in eating plants that required a special carnivore like dentition.
