FIGURE 11. Comparison of the squamosal in right lateral view of Ultrastenos huberi with various species of Baru, showing the angle of descent of the posterolateral process and sculptural elements of the lateral surface. A: Ultrastenos huberi, QM F31075. Note that the lateral squamosal sulcus is both broad and extensive and the posterolateral process descends at a steep angle. B: Baru wickeni, NTM P9464-10 (image reversed for comparison). Note that the lateral surface is largely flat with a short, narrow sulcus and the posterolateral process descends at a shallow angle. C: Juvenile Baru iylwenpeny (NTM P6478). Note the flat lateral surface with a short, narrow sulcus and the shallow angle of descent. D: Adult Baru iylwenpeny (NTM P6515) Note the flat lateral surface with a short, narrow sulcus and the shallow angle of descent shared with other Baru specimens. Note also the presence of a posterolateral boss shared with (B) but not (C). Dashed lines demarcate each posterolateral boss. Hatched areas demarcate lateral sulci. Scale bars equal 20 mm.
