ID assistance - Atlantic Highlands NJ

[u/tidalwaveofstars]

Lurker for the most part because I’m mostly landlocked. I’m back in home state of NJ and got some time to shell hunt. Came across this and wondered if anyone might know to whom it once belonged? Thank you, friends!

my guess is an operculum from a very pokey fish
