. P21283, P218284 and P218286 all represent small odontocete teeth possessing conical enamel-covered crowns that bear fine wrinkling ornamentation, and curve lingually towards the crown apex. As in kentriodontids, there is a lingual bulge at the base of the crown but this feature is not as prominent in the teeth from Portland. None possesses an open pulp cavity suggesting that all were derived from adult individuals.
