Tiny bones ID

[ricardo]

Hello TFF,

I'm very curious about these two tiny bones. Does anyone recognize them? Thank you very much .

Ps. Sorry for the samples being between my fingers, but it was the best way to solve the excessive reflection.

Incus and stapes? Ear bones maybe? Need better pictures to tell.

Hello,

Thank you very much for your kind interest in helping me . I have a feeling they will be bones of a small lizard (Squamata). Given the small size of the specimens, clearer photographs are difficult.
I don't think they're hearing bones, but I'm really out of my comfort zone .

So those bones are in mammals. In reptiles the bones that are the analogs of our middle ear bones are part of the jaws.

Ear bones of cretaceous mammals would be much much smaller than these.  When collecting small cretaceous bones like these, you will always end up with cool little bones that you can’t ID.  That is one way of saying… i don’t know but great little finds.

Dear Scylla and JCP, thank you very much for your help and interest in this matter .

 

These bones were close to an incomplete Squamata dentary, so I deduce that there is a possibility that they are from an aquatic or semi-aquatic reptile (this is a marine, coastal environment), hence I wrote that they probably will not be ear bones, even more so that we would have to have a mammal of very reasonable dimensions. As it is Cenomanian, it is not believable.
