Mosasaur jaw (Halisaurus arambourgi)?

[aplomado]

The seller says it has only a small glued fracture.

What do you all think?

I’m DEFINITELY NOT an expert, but it looks fine to me. You should wait for more people to respond though before making a decision. Good luck.

From just this photo this looks like a good specimen. No red flags at all. Definitely a partial Halisaurus jaw. Hard to tell if this is an upper or lower jaw.
