Figure 4 in Braincase evolution in suchian archosaurs (Reptilia: Diapsida): evidence from the rauisuchian Batrachotomus kupferzellensis

Figure 4. Batrachotomus kupferzellensis Gower. Stereopair photographs and diagram of ventral part of braincase of SMNS 80260 in dorsal view i.e. normal to fracture surface between ventral and dorsal pieces. Anterior is to the top of the figure. Scale bar = 15 mm cr = cohlear/lagenar recess; lr = lateral ridge; pn = notch in break through ventral ramus of the opisthotic for passage of perilymphatic duct; VI = foramen for abducens nerve; vv = ventral part of vestibule; XII = foramen for hypoglossal nerve.
