Table 2. Comparison of the otoliths (taxa and percentage of total) of the Fox Hills Formation (NDGS 5597 locality, near Burnstad, North Dakota, USA), Kemp Clay (South Sulphur River, near Commerce, Texas, USA), and Ripley Formation (near Blue Springs, Mississippi, USA) based on bulk samples. 1 includes specimens identified as Pterothrissus cf. P. conchaeformis, 2 includes specimens identified as Ampheristus cf. A. americanus.
