Loxoplocus Gastropod

I was testing the Canon Powershot Pro1 camera's Super Macro mode by taking some pictures of this gastropod. It looks like the light was bright enough for my images but the camera let me get within 2 inches of the specimen.

NOTE: It was pointed out that this gastropod lived in the Ordovician Period not Mississippian as the picture lists. Also apparently this genus is now referred to as Paupospira.

UPDATE: (2020-08-22) I removed one of the images and updated another to remove the time period reference. Sorry about listing this and I hope the old images eventually disappear from the Internet's image databases.
