Aetobatus Arcuatus Dental Plate

Found within a Gainesville Creek, this is the most complete Ray Dental Plate I've found yet.

Within Page 180 of this link, they say (bottom of the first column, and on the top of second one):

"AETOBATUS ARCUATUS (Agassiz, 1843)

(Duckbilled Ray)

Identification of the duckbilled ray follows Meyer et al. (in press) and Cappetta (1 970). Arcuate tooth plates in the assemblage of abundant myliobatid remains from the Gatun Formation are referable to Aetobatus arcuatus; they cannot be distinguished from the Lee Creek duckbilled ray tooth plates in the SMU and USNM collections.

The species is widespread in the Miocene of Europe and America. It is common in the basal Yorktown

Formation (Pliocene) of North Carolina (Meyer et al., in press) and elsewhere in the Miocene of eastern United States and California, as summarized by Longbottom (1979), indicating Pacific and Atlantic distribution. The only South American record for Neogene Aetobatus is the Ecuadorian occurrence of specimens referred to this genus, but not identified to species (Longbottom, 1979)..."
