Fig. 2From: The pay-off of hypsodonty - timing and dynamics of crown growth and wear in molars of Soay sheepGround sections of labeled sheep molars. Fluorescent micrographs of ground sections of axiobuccolingually sectioned mandibular molars of Soay sheep repeatedly injected with calcein (green labels) and oxytetracycline (red labels). Crown elongation between consecutive injections during different injection periods (of 56 or 63 days) is indicated by brackets. Note marked differences in extension rate between cuspal and cervical crown portionsBack to article page
