Figure 2

Detail of the vertebrae and foramina of the basalmost sauropodomorph Buriolestes (CAPPA/UFSM-0035). Cervical (A–C), anterior (D–F) and posterior (G–I) dorsal vertebrae in right lateral view. Note that nutritional foramina are present throughout the axial skeleton (dark arrows). Anterior/posterior orientation was defined based on the axial position, not the anatomical plane. Scale bar = 5 mm. Figures were generated with Adobe Photoshop CC version 22.5.1 X64.
