Fig. 5 in An ankylosaurid dinosaur from Mongolia with in situ armour and keratinous scale impressions

Fig. 5. Dorsal view of the most distal part of the tail preserved in an ankylosaurid dinosaur Tarchia cf. gigantea, ZPAL MgD I/113 from the Nemegt Formation at Altan Uul III, Mongolia. Five relatively small scutes cover the vertebrae (Types 6 and 8). Two large plates fuse to the centra of the three most distal vertebrae. Note the large grooves on both plates (darkened and arrowed), and the shapes of the distal keels. One handle vertebra is darkened to show the interlocking prezygapophyses and neural spines. Anterior is to the right.
