Final answer:
The tracks of ankylosaurs and ceratopsian dinosaurs suggest more erect forelimb postures than the studies of their bodies.
Step-by-step explanation:
True, The tracks of ankylosaurs and ceratopsian dinosaurs suggest more erect forelimb postures than the studies of their bodies. This means that based on the way their tracks are preserved, it indicates that these dinosaurs walked with their forelimbs held more vertically than what their body structure would suggest. Ankylosaurs and ceratopsians were both quadrupedal dinosaurs, but the trackways show that their forelimbs were more upright during locomotion.
