Figure 18. Comparisons between Sefapanosaurus zastronensis gen. et sp. nov. and Aardonyx celestae. A, middle cervical vertebrae of Sefapanosaurus (BP/1/7409) and Aardonyx (BP/1/6513) in right lateral view depicting diapophysis and postzygapophysis. B, right radius of Sefapanosaurus (BP/1/7435) and Aardonyx (BP/1/6321) depicting the caudodistal tubercle (top) and the distal articular surface (bottom). C, left ulna of Sefapanosaurus (BP/1/7437) and Aardonyx (BP/ 1/5379) depicting the proximal articular surface (top) and the distal end robusticity (bottom). D, left metacarpal I of Sefapanosaurus (BP/1/7438) and Aardonyx (BP/1/5379) depicting the ventromedial concavity. Sefapanosaurus is placed on the left in (A) to (D). Abbreviations: cdt, caudodistal tubercle; di, diapophysis; poz, postzygapophysis; vmc, ventromedial concavity. Not to scale.
