Brachyrhizodus Romer 1942
Description
GENUS † BRACHYRHIZODUS ROMER, 1942
Included species: † Brachyrhizodus wichitaensis Romer, 1942.
Occurrences: Erroneously reported from the Carbo- Permian as a petalodontiform (Romer, 1942), this genus occurs only in the Campanian–Maastrichtian of North America (Cappetta & Case, 1975; Welton & Farish, 1993).
Remarks: Claeson et al. (2010) recently suggested that the Cretaceous † B. wichitaensis Romer, 1942, is a stem-mobuline and not a stem-myliobatid as previously reported by Cappetta (1987). According to these authors, a unique character state supports this reattribution: teeth of † Brachyrhizodus lack any curvature in basal or occlusal view, as observed in living devilrays (Mobula and Manta) and contrary to the genus Rhinoptera. However, observations made by us from the available figurations (Cappetta & Case, 1975; Welton & Farish, 1993) and on dozens of specimens of † Brachyrhizodus allow us to refute the hypothesis of Claeson et al. (2010).
