Peace River Dolphin Tooth Identity?


Harry Pristis

Recommended Posts

I came across another odontocete tooth while rummaging through storage.  I don't find this tooth in Hulberts book.  Does anyone know what dolphin this tooth came from?  It has a triangular, leaf-like root, though one corner is missing in this specimen.

Hi Harry,

 

That's an odd one for Florida but check Goniodelphis in the Hulbert book ("Fossil Vertebrates of Florida" for anyone else not familiar).  I've seen teeth like that from earlier in the Miocene of Maryland, Calvert Formation, where they were called Rhabdosteus by collectors.

I thought about Goniodelphis, Jess, but I couldn't quite make it fit.  Could be a failure of imagination, or just a lack of experience with odontocete teeth.  A quick search didn't reveal anything much about Rhabdosteus except that it is found in the Chesapeake Bay Area.  My tooth is probably river dolphin, an iniid.  This is my Goniodelphis comparison specimen:
