Partial ocean sunfish beak? Or what?

[cck]

A friend found this bone on the shores of the Potomac River in Virginia... mostly miocene marine fauna. Closest we could find was a picture of an ocean sunfish beak from the Calvert cliffs.. but we are eager to hear what others might think? Thanks!

The specimen doesn't look like an ocean sunfish beak to me.  My first impression was a fish hypural also.  Below is a picture of an ocean sunfish beak.

Ah thank you both! I knew someone would know. Ever grateful.

Guess I missed this post earlier, but here for comparison are several hypurals from my collection.

The top one has a broken/missing urostyle and is from a bill fish.

The lower three are tuna hypurals with the urostyles intact.
