Description: MPC−D 100/764, a left humerus of hadrosaurid Saurolophus from the Maastrichtian Bugin Tsav locality in Mongolia, in medial (A) and lateral (B) views (proximal end to the left and distal to the right) with major areas of bite marks indicated by the black arrows. (C) Close up of the medial face of the deltopectoral crest of hardosaurid Saurolophus (MPC−D 100/764) 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. (D) Close−up of bite marks on the on distal end of left humerus of hadrosaurid Saurolophus (MPC−D 100/764) from the Maastrichtian Bugin Tsav locality in Mongolia. Black arrows indicate deep scores that penetrate the cortex on the end of the bone. White arrows indicate deep puncture marks on the surface of the bone.
