Myadora striata, from here.

Belongs within: Pholadomyoida.

Myadora is a genus of free-living bivalves with unequal valves, one flattened and one convex, found from the Miocene to the present day of Australasia and the west Pacific. The valves have a flattened cardinal area on either side of the beaks. Members of the genus live buried in sand with the more inflated valve downwards.
