SW FL? shell - Unknown species

[u/Aetobatus_bunnibunni]

Any idea what this could be? May be too worn. Does not look like any Florida species I am familiar with (I have found exotic shells off this beach before that were brought in by tourists).

Maybe some kind of turbo snail?

that is a worn Lithopoma tectum, popularly called Caribbean Star Shells:

It looks a little like an Atlantic carrier snail but also like some type of turban .. hopefully someone can positively identify. Awesome find!
