Fossil shell from Marano sul panaro 1.9 cm in length.
3 million years old from the Piacenzian age of the Pliocene.
Any help is appreciated

Hey Blackfrog,

Interesting specimen. Can you upload some extra photographs, of the other sides? It reminds me of Cymatium affine, but I am not sure.

Cheers,
Johan

Still think it is a Cymatium. But I do not know the exact species.... Would it be possible to make an extra close-up of the mouth? The number of teeth is usually an important characteristic.

Cheers,
Johan

I can count up to six teeth in the aperture (my camera can't get that detail in, it just loses focus trying to do it -_-

Based on what I can see, I thick that this would be Cymatium affine. This is one of those species of Cymatium that only relatively minor axial ribs, and usually 6-7 teeth. I am not entirely sure though, of my identification, as the Pliocene of the Mediterranean is not my personal expertise.

Cheers,
Johan

I think it could be something else.
In photo a Cymatium from the same site and the shell in need of identification.
The axial ribs along the last whorl seem to be much bigger in the Cymatium up in the photo compared with the smaller shell on the bottom.
also the teeth in the Cymatium are much bigger than those of the one in the bottom (could be due be different quality of preservation).

You're right, that does look rather different. I wouldn't exactly know what else it could be..... Difficult!

Right now I temporarely classified it as "Ocinebrina sp.".
Still not convinced about it though

I hadn't thought in that direction. I think you are right about Ocinebrina. But what species could it be???
