Patterns of morphospace occupation for herbivorous nonavian ornithischian and sauropodomorph dinosaurs. PC1 and PC2 account for 50.4% of variation. Ornithischian and sauropodomorph taxa occupy significantly different regions of shape-based morphospace (p<0.05). Filled circles, Sauropodomorpha; open circles, Ornithischia. Silhouettes represent jaw profiles found in that region of morphospace.
