Figure 1. Tapuiasaurus macedoi (MZSP-Pv 807). A, skull in quarry, with left side exposed and showing the position of the lower jaws, and ceratobranchials. In addition, the anteriormost cervical ribs are positioned just posterior to the ceratobranchials (parallel, nearly vertical splint-like elements); they most likely pertain to the axial vertebra. B, skull in early stages of preparation, with right side exposed. Note that a small portion of the surangular was damaged in the initial stages of preparation; more of this region of extremely thin bone was lost during subsequent preparation (compare to Fig. 16).
