Fig. 12D–G

“genus Congridarum ” prolatus Müller, 1999: 83, fig. 21/11–14.

“ Congrida ” prolata – Nolf 2013: 36, pl. 27.

Remarks

The otoliths of “ C. ” prolatus are characterized by a relatively elongate shape, a wide sulcus, an ostium opening widely to the antero-dorsal rim, and a small dorsal depression. The combination of these characters may point to an extinct taxon within the family Congridae .

Stratigraphic and geographic distribution

Lutetian: Piney Point Formation, Virginia.
