   @pasadena85 I would say bivalves, since it is asymmetrical in a planar view.

   @neufotomacher well..but brachiopods are made up of two valves which are different sizes and possibly shape, whereas the two valves on a bivalve are the same (symmetrical). Brachiopods consist of a top and bottom valve whereas on bivalves they are referred to left and right valves, therefore I tend to say these are brachiopods because of their asymmetrical shape...?

   @pasadena85 Some Trias oder Juras Trigonia bivalve, I would say.
