Figure 7. Comparing Trackmaker A prints of Lark Quarry with the Australovenator prints to help identify various morphological features of the Lark Quarry prints.

(A) Trackmaker A LQ1 (left foot), with a distinct claw trace of digit II; (B) Trace of morphological features and print outline of LQ1; (C) Graphic depicting the movement of the Australovenator foot used to create (D); (D) Australovenator print with a full heel contact similar to LQ1; (E) Trackmaker A LQ3 (left foot) is the longest print of this trackway; (F) Trace of morphological features and print outline of LQ3; (G) Graphic depicting the movement of the Australovenator foot used to create (H); (H) Australovenator print with a slight heel slide creating a slightly longer print similar to LQ3; (I) Trackmaker A LQ4 (right foot) has been restored in situ around the heel region and digit IV giving the heel a rounded appearance; (J) Trace of morphological features and print outline of LQ4; (K) Graphic depicting the movement of the Australovenator foot used to create (L); (L) Australovenator print with full heel contact, favoring the lateral side creating a wider fourth digit impression, which formed a rounded heel impression (generally regarded as characteristic of ornithopod prints) which is similar to LQ4; (M) Trackmaker A LQ5 (left foot) favored the medial side when entered into the substrate with an exaggerated heel slide. Some claw traces following kick-off are also visible; (N) Trace of morphological features and print outline of LQ5; (O) Graphic depicting the movement of the Australovenator foot used to create (P); (P) Australovenator print favoring the lateral side with full heel contact and slight rotation to simulate direction change. Abbreviations: claw trace (c), suction of substrate to the foot causing suction trace (s), tunnel features of the digits (t). Arrows depict direction of movement.
