Ouranosaurus Following the Wavy Trail
Seen from the side, the dinosaur travels on four legs over a sandy landscape. Wavy marks cross the ground near its feet, while gentle hills form the distant background. The tall ridge along its back gives the animal a distinctive profile.
Reading Trails in Sand
Tracks and winding marks last longest when sand or mud is damp enough to hold their shape and is then covered by another layer of sediment. Fossil trackways can reveal an animal's direction of travel even when no bones are found nearby. The high spines on the back of Ouranosaurus supported a raised structure, although scientists still debate exactly how that structure looked and functioned.
