Figure 14. Reinterpretation of the neurocranium of Griphognathus minutidens. Anterior is to the top. A, photograph of NRM P6173, showing otic and occipital regions in ventral view; B, interpretive drawing (modified from Schultze, 1969). Shaded area in B indicates portions of the otic and occipital region underlain by the missing portions of the parasphenoid stalk and corpus, while diagonal hatching indicates damaged bone surface. The apparent foramina on the wall of the otic capsule have been interpreted as accommodating cranial nerves by Schultze (1969), but this specimen is badly crushed and uncertainties about these identifications are indicated by appending them with '?'. The unossified facet for the first epibranchial was initially mistaken as a foramen for a ventral branch of the acoustic (VIII) nerve (Schultze, 1969). Scale bar represents 10 mm.
