What you have is the posterior portion of a fish mandible, known as the articular.
How did you know that?
My background is in zooarchaeology, so I've spent a lot of time identifying and analyzing bones from archaeological sites. (Although I'm not good with fish and reptiles. Mostly mammals and birds where I'm at.)
Neat!
