Teeth Pleistocene

[jamhill]

Two teeth here. I think both are from the beach in Jacksonville Florida. Although, the first might have been from a phosphate mine. I can’t remember. They look like they might be canines? 

[Lorne Ledger]

Both mammal and carnivore.  Second one looks like an otter canine to me.  First one I am getting a P1 Bear vibe.

i am no expert but I would have called the second tooth dolphin, and even possiblly the first as well-- particularly from florida.  To me they look similar to other teeth id'ed as dolphin on the forum (see photos taken from other forum posts)  the last photo was identified as river otter, to me it has a much greater curvature between the tooth crown and root.

Hi,

I agree that both are from Odontocetes. Probably dolphin.

[jamhill]

Thanks everyone. 
 

After further googling, bear p1 looks very similar to the first but I can’t find any good close up pics of that specific tooth. 
 

10313horn and sixgill Pete I think you two might be right on the second. The second tooth does look like some of the dolphin teeth images. One thing that may be hard to see in the pictures is that the second tooth is flatter. Are dolphin teeth flat?

[Lorne Ledger]

I'll change my opinion on the second tooth to Dolphin also, if it isn't then it is an upper left canine possibly a strangely worn racoon. Caveat to that possible ID tho, it is very round and straight looking which is why I thought otter (or possibly small cat).  Will see if I have a bear P1 to officially compare, I should

[val horn]

i would love to see a p1 bear.

Here are some pictures of black bear mandibles I have, your tooth is much bigger so thinking it might be Arctodus pristinus.  Hellava great find if so.

Hope this is helpful

Not disagreeing, but upper River Otter canine have a much less severe curve.

i become more impressed by how difficult it is to  fully id isolated teeth.  I think i still favor dolphin for those teeth from florida  as much as for shape (which they  still match, even if it might match others,)  and for frequency in either bone valley  material, or from what I have seen on the east coast.  It may be time to think of referring to true experts University of florida dept of paleontolgy gainesville.  Below is the Univerisity's info.  they were really nice to me when I dropped by before covid.

 

There are three basic methods we prefer:

• Electronic Images. Send us digital images of specimens either as e-mail attachments in JPEG format (to rhulbert    at  flmnh.ufl.edu) or post them on your own web site and e-mail us the address (URL) of the site. Please include a ruler or some other indication of scale in the image. Take pictures of more than one side of the specimen.
• Bring the Specimens to Dickinson Hall. Those in the Gainesville area can bring their specimens directly to us. We are located on the UF campus on Museum Road, just up the hill from the UF Health Hospital/Research complex. You will need a temporary permit to park on-campus. We recommend that you call or e-mail us and make an appointment, as sometimes all our personnel are out in the field or otherwise unavailable. Our phone number is 352-273-1930. When reaching Dickinson Hall, go in the front doors and ask the receptionist to page us. Available hours are M-F, 9-5.
• Mailing Specimens. Mail or ship specimens to: Div. of Vertebrate Paleontology, Florida Museum of Natural History, Dickinson Hall, Univ. of Florida, Gainesville, FL 32611-7800. Pack fossils as you would fragile china. We recommend wrapping each specimen individually in bubble-wrap or soft paper, placing them inside a padded box, then put the boxes with specimens in a larger, sturdy box cushioned with packing material. Make sure to include a return address and phone number within the package. We are NOT responsible for damage done in transit both to and from the museum.

Hi,

 

It is often said on this forum that you should never put a clickable email because it will be quickly taken over by robots and spammers. But here, you don't put yours, but that of another person (I imagine without his consent). He won’t be happy when his email is full of spam !

 

You have to write rhulbert -@- flmnh.ufl.edu or any way as long as it’s not clickable. Please correct it !

It is already posted on a public website from where the member cut and paste from: https://www.floridamuseum.ufl.edu/vertpaleo/amateur-collector/fossil-id/

 

Also, most university email servers have strong spam filters (sometimes overzealously so).

OK, but the risk still exists.

As much risk as the email already appearing on a public website.  

[val horn]

  it is easy enough to fix, and i did not even think about it-- whoops.

I have seen a lot of dolphin , especially the rare Harbor dolphin which had spatulate teeth from Florida.  Your 1st tooth resembles a Harbor porpoise tooth, but I do not think it is.  Richard Hulbert is one of the few who could identify a Ursus p1 if that is what you found.

Hey all, finally back on here - I agree that both are from carnivorans rather than cetaceans. The little short tooth could also be a lower seal incisor - in some species they are quite low like that.

[fossillarry]

I also believe the first tooth is a lower first premolar of a bear.
