Fig. 3 in Macroevolutionary and morphofunctional patterns in theropod skulls: A morphometric approach

Fig. 3. Two−dimensional morphospace of the theropod skull shape (large data set) with distribution of the different theropod clades, based on the first two PC axes. The most derived taxa with respect to the first two components are visualized with relative warps. Shape changes along PC 1 reflect changes in the length and height of the snout and the anteroposterior dimensions of the lateral temporal fenestra. Changes along PC 2 reflect the height of the postorbital region, the size of the orbit and the position of the jaw joint.
