Patterns of morphospace occupation for herbivorous nonavian dinosaurs through the Mesozoic (20 Myr time bins), based on PC1 and PC2 (accounting for 50.4% of variation). Sauropodomorpha occupy isolated regions of morphospace for the majority of the Mesozoic, with overlap between North American sauropods and thyreophorans between 185 and 145 Ma.
