Table 3 in First Cretaceous teleostean otolith assemblage (Arkadelphia Formation, upper Maastrichtian) from Arkansas, USA, early Gadiformes, and the Western Interior Seaway

Table 3. Percentage similarity measurements for the otolith assemblages from the Arkadelphia Formation (Cabot locality, Arkansas, USA), Fox Hills Formation (NDGS 5597, North Dakota, USA), Kemp Clay (South Sulphur River locality, Texas, USA), Ripley Formation (Blue Springs locality, Mississippi, USA, and Severn Formation (five sites, Maryland, USA). Data for calculations were obtained from this study (Table 1) for the Arkadelphia Formation (Cabot locality), from Hoganson et al. (2019) for the Fox Hills Formation (NDGS 5597 locality), from Schwarzhans and Stringer (2020a) for the Kemp Clay (South Sulphur River locality), from Stringer et al. (2020, table 2) for the Ripley Formation (Blue Springs locality; bulk samples only), and from Stringer and Schwarzhans (2021; table 3) for the Severn Formation (four sites).
