Figure 12 in Cranial anatomy of Shunosaurus, a basal sauropod dinosaur from the Middle Jurassic of China
Figure 12. Diagrammatic view of the jaw occlusion of Shunosaurus during feeding. A, comparison of dental margin of Shunosaurus with a pair of garden shears.

Upper and lower tooth rows interdigitate and shear past each other so that each lower tooth fits between two upper teeth along their lingual surfaces. C, one bite cycle procedure for shearing stems and branches.
