Cererithyris arkelli
Today's fossil is Cererithyris arkelli from the Bathonian stage of the Jurassic (164-167 mya). These were collected from Luc sur Mer in the providence of Normandy, France. It is a Terebratulid and shows just a little bit of plication (the zig-zag folds) near the front edge of the mature shells.
