Figure 5

Patterns of biomechanical morphospace occupation for herbivorous nonavian dinosaurs through the Mesozoic (20 Myr time bins), based on PCo1 and PCo2 (accounting for 25.2% of variation). Sauropodomorphs predominantly overlap only with heterodontosaurids (202–145 Ma). Aptian–Maastrichtian marginocephalians and ornithopods occupy similar regions of morphospace (125–65 Ma).
