Permian maxilla w/ teeth?

[Mochaccino]

Hello,

 

Could I get an ID on this piece? Permian-aged from the Ryan Formation near Waruika, Oklahoma. It's labeled as a reptile jaw piece. Has three teeth that are laterally compressed and somewhat twisted with serrations (Apparently there are serrations only on one side of the teeth). I wonder if it's shark and not reptile at all. Pathological shark tooth perhaps? Size is a little over 1cm.

How do you get such wonderful closeups?

I think so. Looks like some type of Orthacanthus.

That tooth arrangement doesnt look correct for a xenacanthid shark. I dont see evidence of the tooth base either.

I'm seeing a pathological Orthacanthus tooth, too.

These are photos from the seller, not taken by me. I only have a crappy phone camera so can't take great close-ups!

Thank you, I was thinking some sort of shark, and those get pathological teeth fairly commonly.
