I'm not the best with tooth ID's, since most of the mosasaur teeth I've seen in person come from basal Plioplatecarpines, whose teeth are mostly indistinguishable. But, realizing this broken apex from a much larger tooth lacked fine striations and had a faint anastomosing texture made me suspect a mosasaurine origin, as opposed to the most common large mosasaur from the Ozan - Tylosaurus proriger. @pachy-pleuro-whatnot-odon was kind enough to walk me through the ID points and converged on indeterminate Prognathodon sp., and paleontologist Mike Polcyn gave the same opinion. Prognathodon is not described from the Ozan formation, making this an exciting find. There seems to be an elusive giant still lurking Texas's most iconic formation.
