Harry Pristis Posted June 1, 2015 Share Posted June 1, 2015 Here are a couple of periotics (ear bones) from small, toothed whales from the Miocene-Pliocene of South Florida. I don't know more than that about them, so I'm hoping that someone here will have an identification. Such periotics are found from time to time in the Peace River, but they are not well known to collectors. And for comparison: http://pristis.wix.com/the-demijohn-page What seest thou else In the dark backward and abysm of time? ---Shakespeare, The Tempest Link to comment Share on other sites More sharing options...
Boesse Posted June 2, 2015 Share Posted June 2, 2015 Hi Harry, The periotic and bulla are both good matches for pygmy/dwarf sperm whales - Kogiidae - there's something called Kogiopsis floridana, but known only from a mandible described in the 40s. There's Aprixokogia from the Pliocene of Lee Creek, but is known from a skull - and not earbones. So, for the time being, we have to accept "Kogiidae indet." for finds like this. AKA Kogiinae in some of the literature. That's a pretty periotc. Bobby 2 Link to comment Share on other sites More sharing options...
Harry Pristis Posted June 2, 2015 Author Share Posted June 2, 2015 Thank you, Bobby! I am happy to have some identification so I can put these bones into my drawer. ---HP http://pristis.wix.com/the-demijohn-page What seest thou else In the dark backward and abysm of time? ---Shakespeare, The Tempest Link to comment Share on other sites More sharing options...
Harry Pristis Posted June 2, 2015 Author Share Posted June 2, 2015 Bobby . . . Darned if I didn't find another petrosal in my drawer, this one labeled "sperm whale." It's from the Peace River, so it's likely to be Late Miocene to Early Pliocene like the kogiid you identified earlier in this thread. I've photographed it alongside that kogiid for comparison. What do you think this is? http://pristis.wix.com/the-demijohn-page What seest thou else In the dark backward and abysm of time? ---Shakespeare, The Tempest Link to comment Share on other sites More sharing options...
Boesse Posted June 3, 2015 Share Posted June 3, 2015 That's definitely another sperm whale (Physeteroidea), possibly another kogiid. It looks closer to a kogiid in the spatulate posterior process (bottom feature of the right-most photo). Link to comment Share on other sites More sharing options...
Doctor Mud Posted June 3, 2015 Share Posted June 3, 2015 Where would we be without Bobby? P.S. How's life post PhD Bobby? You said earlier that you had submitted. I'm sure you won't have any problems continuing on your academic journey! Good luck with the job hunt. Link to comment Share on other sites More sharing options...
