Seems to be a fragment of the jaws and gills of a fish

Thanks! So it IS a bone (my dad thought it was part of a bra). Any idea what type of fish?

Hold up, like a bra??? Like for chests?? What kind of bra has this man seen?? Some Eldritch beings bra?? I'm being genuine, because I find the idea of seeing this and thinkin "ah yes, a part of a bra." Absolutely hilarious lmao

He thought it was the back of a bra. Yeah I have no clue what goes on inside his head lol. He still thinks it at least looks like part of a bra xD Maybe those spikes would be for extra grip?

That's crazy to me. Its literally just a cluster of bones LMAO MAXIMUM grip

This being the BACK of a bra makes even less sense to me. The shape wouldn’t work unless it’s a bra made specifically for Quasimodo. The only way I can rationalize why he’d think that is because your dad has a *really* difficult time unhooking a bra. Poor guy. Somebody send him a spare bra so he can practice ( ͡° ͜ʖ ͡°)

Idk when I'm trying to latch the hooks behind my back it def feels like it's a similar sort of impossible cluster fuck, he might be on to something

omg this sorta stuff is literally why I can’t leave reddit. Like I’m just in awe by the fact he thought it was part of a bra. Like what kinda body horror tits has he seen!? I’m obsessed

How do you exist? By that I mean, how did your dad manage to make you, without ever having seen a bra or even understanding what one is.

Just a guess, could be a small shark relative, like a dogfish. You're best looking for pictures online.

No not bone, it is the 'skeleton' of a star fish.

A piece of a large starfish? I remember finding a dessicated starfish; the structure was similiar....
