Joy,

By sheer coincidence, I saw your question just before leaving for a
presentation at my local dive club meeting by a scientist who dives in
Antarctica.

He showed images of scallops (and sea urchins and starfish and forams).

He said that it was previously believed that the sea level was far higher in
the recent past because scallops were found on the sides of mountains
nearby. However, scientists have since figured out that scallops locked in
patches of bottom ice (formed by contact with the colder substrate) can
float to the top where they are blown by surface winds to higher elevations.
