jbstedman Posted March 30, 2009 Share Posted March 30, 2009 I think this is a periotic (one of the ear bones) from a dolphin, but I'm not sure. Looking for confirmation or alternative IDs. This specimen is from the Calvert Formation, Miocene. The two images show one side and the opposite. I have no idea about the orientation of this bone in the animal. Besides fossils, I collect roadcuts, Stream beds, Winter beaches: Places of pilgrimage. Jasper Burns, Fossil Dreams Link to comment Share on other sites More sharing options...

Boesse Posted April 2, 2009 Share Posted April 2, 2009 Jbstedman, Your periotic is from a "kentriodontid" dolphin. It shares some similarities with Nannolithax, originally reported only from California, but recently also from Lee Creek. I'm not terribly familiar with the earbones of east coast cetaceans, but it should be identifiable to a known kentriodontid. It shows some strange features, for sure, but appears also to represent a juvenile. Bobby Link to comment Share on other sites More sharing options...
