inner ear bone

[Brownie_r]

Does anyone know what type of ear bone these might be?

Can you please tell us where they were found? We can't ID them without that information.

These somehow do not look like fossil bone to me.

They reminds me of calcite flowstone .

I am OK with Fossiledude19.

Can we see some additional photos. What do the opposite sides look like. Does the top one have a cavity/void of some sort? They are interesting suggestive shapes to say the least, particularly the lower specimen. Are they creek finds? or directly removed from some type of strata?/rock? Are there other types of mammal fossils present?  Any geologic/providence info available for them?

Yeah,I am curious why this is considered odontocetacean(given the tags).

I am nororiously bad at recognizing anatomical parts.

I don't think i see a processus petrosus or p. sigmoideus here,but I could be totally wrong

[Doctor Mud]

The bottom specimen certainly looks like bone and the type of bone structure of an earbone (periotic) but not one I'm familiar with.

 

Another case for @Boesse who will probably recognize it in a heartbeat

Dr Mud,after having trundled thru oodles of cetacean cranial/neurological/audition/ear ossicles/histology lit.,I realize you might be right.

Boesse's ability to recognize any part of the cetacean skeleton never ceases to amaze me.Ok,he's a specialist,but still..

Please excuse my naivety with all of this. I found them quite a few years ago by a river. They were in the sand with a bunch of rocks. I didn't see anything else that resembled fossils; no other kinds of rock formations or anything. They were out of place it seemed.

Perhaps this will help.. I love old TFF threads:

Your finds are definitely mammal inner ear bones. Perhaps Equus, like the one in this thread. I have never been able to differentiate between, horse, bison, camel, predator, tapir, etc and I make the assumption that all of those and more are present as fossils in the Peace River Florida.  They are exceedingly rare,  but few hunters recognize them.  I find about 1 a year hunting.  You could send photos to Richard Hulbert at the Vertebrae Research Lab for identification. https://www.floridamuseum.ufl.edu/vertpaleo/amateur-collector/fossil-id/

Thank you!

Hi all,

 

In my opinion this petrosal bone is a pretty good match for horse - Equus. I recently spent some time trying to identify a similar specimen from Charleston SC which I had hoped would be an anthracothere; turns out it was a pretty good match for Equus, and is very similar to this specimen.

[Plantguy]

Awesome! Neat to see other views of the specimen and ID confirmation.

My original mammal petrosal earbone was Llama-camel

Back in 2009-2011, I thought I would be able to identify large numbers of fossil mammal earbones, but Tempus fugit. I have only identified Horse and Llama.
