Guest bmorefossil Posted June 21, 2008 Share Posted June 21, 2008 here is a part of an earbone from my partial skull of a dolphin/ small whale, i like to call it the alien because of its shape. Im just getting back to putting it together and now that school is out i will finally be able to. I hope someone can i.d. it for me i have never been able to. Its 18-15 million years old and from the calvert formation here in maryland Link to comment Share on other sites More sharing options...

Boesse Posted June 22, 2008 Share Posted June 22, 2008 The tympanic bulla appears to be very similar to that of Parietobalaena palmeri, which is the most common baleen whale in the Calvert Formation. That is an exceptionally small tympanic, and it appears that you have a juvenile. Bobby Link to comment Share on other sites More sharing options...

Boesse Posted June 22, 2008 Share Posted June 22, 2008 Eubalaena doesn't really look anything like that; I suspect the photo is either mislabeled, or is extremely small. Eubalaena's tympanic is about 5-6 times the size of your tympanic, and perhaps even bigger than that. Additionally, the involucrum (the big bulbous part) is flattened or pinched in Balaenids.
