Hello,
and another bivalve from the Miocene Styrian basin of Austria. It has some resemblance with Anadara diluvii, but I am not totally sure. It is associated with a brackisch fauna (Crassostrea gryphoides, Pirenella picta, Terebralia bidentata).
For comparison a typical Anadara diluvii from the same area, but another locality, is also attached (size 2 cm). This type is also abundant at other localities in the area (typically with marine fauna).
All suggestions and comments are greatly appreciated!
