Found these on the beach. I’ve seen pictures of them before but I can’t remember what they are. We’re they bone plates? Teeth? Idk.
They’re pharyngeal tooth plates from a large fish, maybe a sheepshead or a black drum. Not sure which kind, you’d want to look up what tooth-plate-containing fish are native to the area. Those plates are in the back of the throat, and the fish uses them to crunch on shelled inverts. Awesome find!
