The bone structure certainly looks "fishy".

Here is a photo of the inside of a tylosaur jaw, it looks a lot like yours, with the empty sockets.

In Falcondriver's pic, the teeth are much closer together, and the grain of the bone is very different.

I was thinking Clidastes. They are smaller with closer teeth. That photo is before the bone was cleaned. If you go to my gallery and look at the mosasaur skull you will see that it is similar in texture.

Thanks for the help Mike!

Pretty sure that is a Pachyrhizodus fish jaw. They look a lot like mosasaur, but that's def a fish jaw. The teeth are too short and regular in size for Xiphactinus and too heavy for Ichthyodectes.

Here's the partially prepped skull of a very large Pachy in our collection...note the similarity of the teeth.

I agree almost certainly Pachyrhizodus

So what is the final say so?Bird or Fish? :mellow:

Speaking from the area of my aspiring expertise, not bird.

After looking at the fish skull, I'm changing my guess to Pachyrhizodus too! :P
