Odd mismatch between the 1st

Odd mismatch between the 1st view & the wavy outline of the 2nd

separation

The mismatch may be significant but the teeth arrangement and Pallial Sinus are pure Dosinia. Separating exoleta from lupinus is not easy, even with such good pictures.
The picture on the right is strongly similar to D.exoleta.
I believe the wavy outline is the result of sea-wash-sand abrasion (wear) - I have a LOT of those!
