Miosen bivalvia

[ozgur70]

A small one. 15 mm. 

The bivalvia fauna of Miosen in Karaman basin is really amazing.

Turkey, Karaman.

Once again @Max-fossils

Very nice!  Love the ornamentation.

 

We certainly don't have anything resembling that on the US East Coast (my reference point)

Very nice specimen!

[Max-fossils]

Beautiful!

It's definitely something from the Cardiidae family, and it personally reminds me of something from the Acanthocardia genus (but that's not certain). 

After doing some research there seems to be a document that describes the fossils of your locality:

Mollusques du Neogene des Bassins de Karaman, Adana et Hatay (Turquie), Ankara

I've tried finding it online, but I can't find a PDF version... I'm sure that all the species are described in there, so if anyone has a free PDF version of this please let us know!

Best regards,

Max

Thanks Max.

Very close to Acanthocardia echinata...

Only there is a diameter problem. My findings are 10-17 mm.

Acanthocardia echinata does seem similar but it's almost definitely not that species: size is the first difference, and secondly the size, shape and distribution of the little spikes is definitely not consistent with that species. But yes, it's somewhere in that area, and the document I talked about would be the best to propose an adequate species.

@ozgur70, again very similar shells here in the Styrian Basin of Austria ("Florianer Schichten", Langhian):

https://www.franzbernhard.lima-city.de/Herzmuscheln_1.html

These have been identified as Acanthocardia paucicostata since then.

And again: I don´t think that yours are the same species, they are just somewhat (very) similar... . @Max-fossils

I find the book.  And it was called as Cardium (Cardium) paucicostatum. You are right. Thanks.
