Marine Mammal

[Shellseeker]

I have acquired 2 Marine mammal fossils in the last few days. One is a dolphin periotic found in the Peace River Thursday.

@Boesse walked me thru the identification of this find a couple of years back

Pomatodelphis is an extinct genus of river dolphin from Middle Miocene marine deposits in Alabama, Florida, Brazil, Germany and France.

 

I thought it was similar to a river dolphin, but when I examined it today,  it is about the same size but otherwise.... not so much

 

Here are a few other angles

 

While I have previously found a number of Dolphin periotics in the Peace River, this one seems more complex than the others.

 

 

@gigantoraptor has offered some fossils for sale,  including some STH marine mammals.  He had this bulbous rooted whale tooth which I purchased.  I am attracted to them and solicit any comments or identifications from whale tooth enthusiasts.  !!  Right now ,my only guess is Scaldicetus .sp.

OK that first periotic is from an extinct kogiid sperm whale - commonly found at the Lee Creek Mine as well as some localities in Florida including the youngest assemblages in the Bone Valley Fm. We've found them in Pliocene and early Pleistocene strata in South Carolina. Genus is uncertain. Figure from Velez-Juarbe et al. 2016: JVP.

Thanks to Jack @Shellseeker and Bobby @Boesse for this thread.  I have each of these and didn't realize there was a difference in genus until now!

I'm confused.  Bobby addressed only the first periotic, didn't he?  So, what are the two genera (families?) to which you are referring?

 

[PODIGGER]

My take was that Bobby was saying the two periodiotic  pictured were different genera. If not then I  misunderstood his post.

Sorry, I didn't bother with the second one since it looks like Pomatodelphis to me and I think the ID is OK.
