Remarks

The two otoliths from the “Stone City beds” (Texas), here named “ O.” aff. rhomboidalis, are very similar to those of the “ O.” rhomboidalis from the European Ypresian. The concerned American otoliths are somewhat higher and have a shorter rostrum.

Stratigraphic and geographic distribution

Lutetian: “Stone City beds”, Texas.
