 Unilateral branch stripping is the most likely feeding behavior of "Diplodocus", as it explains the unusual wear patterns of the teeth (coming from tooth–food contact).In unilateral branch stripping, one tooth row would have been used to strip foliage from the stem, while the other would act as a guide and stabilizer.With the elongated preorbital (in front of the eyes) region of the skull, longer portions of stems could be stripped in a single action.
