Fig. 2 in New information on scavenging and selective feeding behaviour of tyrannosaurids
Fig. 2. Close up of the medial face of the deltopectoral crest of hardosaurid Saurolophus (MPC−D100/764) from the Maastrichtian Bugin Tsav locality in Mongolia. Black arrows indicate some of the drag marks left by the teeth of the theropod, with their orientation also indicated by the direction of the arrow. The grey arrow points to a bite and drag mark where a slight surface drag mark later goes deeper into the bone cortex close to the edge of the crest.
