French gastropod: Pleurotomariid (slit shell) internal mold, probably Mesozoic.

Mexican shells: Info is a bit confusing in that "left" and "right"
refer to the photo with both shells, while the individual pictures
have the opposite specimens to left and right.  The cowrie has a worn
back, probably human-caused, hence not being smooth nor looking like
normal species.  The other shell is marginellid.

Texas gryphaeid: Exogyra is a likely genus.

Milford on Sea: The general area has good Eocene outcrops along the
coast, but I don't have exact local geology at hand.
