Remarks

The otoliths of “ Conger ” websteri show some similarity to those of “ C. ” prolatus (see above), which might indicate a relationship. The dorsal rim of the latter species is slightly elevated in the middle, whereas it is flat in “ C. ” websteri. The species is also known from the Bartonian (Barton Clay) of Southern England.

Stratigraphic and geographic distribution

Lutetian: Piney Point Formation, Virginia. Bartonian: Cook Mountain Formation, Mississippi.
