“ Neobythites ” constrictus Stinton, 1977

Fig. 7B

An oblong otolith from the Rappahannock River locality in Virginia possesses an obtuse, moderately protruding rostrum and a sulcus type most similar to “ N.” constrictus from the Ypresian London Clay of southern England. The more compact outline of the otolith and flatter inner face are considered as size-related intra-specific variability.
