Myonia ssp. Clams

These Clams are found in the Branxton formation, they are often very detailed and articulated (although squished a little)

But they are often not complete, you will find fragments of them like these....the top one is complete, it was burried in life position, perhaps pushing up through the sand trying to get the the surface but was preserved vertically and squished completely down over time....the beak and hinge are intact on the back.
