Partial shark tooth from the Finis Shale of Texas

I thought I had already posted this here for a better Id but couldn't find it with a search so I'll show it now. I originally thought it was about half of the original but an image on Facebook suggested it could actually be a third of one possible  Agassizodus sp. tooth.

Wayne Itano would go no farther than saying "probably, in the order Eugeneodontiformes. I wouldn't rule out the order Orodontiformes."

It's from the Finis Shale member of the Graham Formation, Late Pennsylvanian of Jacksboro, Texas. Scale is millimeters.
