Help needed for ID Miocene - Pliocene, or Upper Eocene, Mollusks from south central Chile

[terminatordiego]

Hello again to all of you guys , I´m in a huge need oh help to ID some mollusks of south central Chile.

Currently these are storaged in the vault of a local university.

I know taht the fossils in the images are not in the best conditions, but the outcrop itself

sadly has been seriously reworked by a bulldozer machinery (they may be a little bit flattened). At least to a family or genus level ID should be nice considering how they actually are.

The beds should be of the Miocene to Pliocene. But also theres a very minor chance of being from the middle to upper Eocene.

The larger axis of each cabinet is around the size of a fist.

Here the photos:

 

 

 

 

 

 

 

 

 

 

 

Thanks again and greetings from Chile!!!

Yeah, they look remarkably similar to Cenozoic molluscs at the other side of the globe. But belong to completely different genera etc.

Could be veneroid, tellinid etc. bivalves, though.
