This fell out of a powdery clump around a shell. (after flood=gooey crumbly mess) I feel like it's probably broken bits of shell, because they look situated on a shell fragment. The way they're lined up, however, looks weird. (As so much does! Lol) So basically, I'm not sure if I should toss it, or if it might be teeth? Really, really hard to get a closeup of the detail. There are three (I think), they're shaped kinda like teeth...the one that's exposed the most has a groove down one side, I can't really see the other side of it. Sw Fl.
