Rhynchoconger sp. 2

Fig. 10E–F

Remarks

Otoliths of this taxon show a reasonable resemblance to the Maastrichtian (Kemp Clay) Rhynchoconger brettwoodwardi Schwarzhans & Stringer, 2020 ( Schwarzhans & Stringer 2020), but most of our specimens of Rhynchoconger sp. 2 have a slightly hollow upper part of the posterior rim and lack the more prominent expansion of the antero-dorsal portion. Therefore, they probably represent a different species.

Stratigraphic and geographic distribution

Bartonian: Wheelock Member, Texas.
