Could you please help me identify the animal or fish that this bone came from? It was found on a beach in Nicaragua.

Thank you

Hi Tim, after asking some experts that are fish specialists, it seems the best guess is a ventral armour plate from a catfish.  However, from the one photo it is very difficult to tell.

Hi Tim,

as Peter says, it's hard to tell from one photo, but this looks quite a lot like the hypoplastron of a marine turle to me, rather than being from a fish.
