After publication, it came to the authors’ attention that the Diceratherium specimens from the John Day localities used in this study are now recognized as two species, Diceratherium armatum and Diceratherium annectens. Diceratherium niobrarense is still applicable to other Diceratherium populations during this time period, but is no longer considered appropriate for the John Day specimens.
