ID Help with Small Bones - Pleistocene, Peace River

[Bone Daddy]

Here are two small oddball bones that I found. Both appear to be complete or mostly complete, but they have odd shapes that I am having difficulty making sense of. This is especially true for the last one, which is shaped like a human ear (I know it's not that, LOL, but that's what it reminds me of).

 

Both were found in my sifter on the Peace River at Gardner (Pleistocene?, Bone Valley, Florida)

 

Any help would be appreciated.

I think those are bones of wrist or ankle, but i can't help you further.

Human'wrist and ankle bones for comparison :

These ankle bones are usually difficult to ID from images.  I have spent years reliably identifying and collecting these bones in a comparison collection.  Here is a starter collection to look over to see if you see something similar to your bones.

Thanks Harry. This is definitely helpful. The "ear" bone is similar to the camel navicular and unciform. The bison ectocuneiform is also similar. I think it's an ankle bone, but yes, it is tough putting an exact ID on these - some of them share similar features.

 

Another bone that turned up in my sifter (that I didn't post) is very similar to the horse magnum and now I need to take another look at that one.

 

Thanks Harry!

I am really curious about the oddball "ear shaped" bone. So, I cleaned up my photos better and sent them to Dr. Hurlbert. I'll let everyone know what he says when he gets back to me.

 

I'm fairly certain that it is an ankle bone of some sort. Harry pointed me in the right direction with that I think.

Dr. Hurlbert got back to me already.

 

He said the "ear shaped" bone (the first one) is an ankle bone from a horse (equus) or tapir (tapirus). He said it is a navicular bone.

 

The second bone, he said it is a wrist bone (scaphoid) from a llama.

 

Pretty cool. Both are bones I have never found previously. 

 

Thanks again to @Harry Pristis for pointing me in the right direction!
