Fig. 10 in The beaver Steneofiber depereti from the lower Upper Miocene hominid locality Hammerschmiede and remarks on its ecology

Fig. 10. Wear stages (WS) and step-length between between wear stages for the lower premolar dp4/p4 of the beaver Steneofiber depereti Mayet, 1908, from the early Late Miocene locality Hammerschmiede (Bavaria, Germany). The step-length of wear stages is given as an approximate percentage of the entire p4 tooth crown height (100%). Lower right dp4 (GPIT/MA/10785) in buccal (mirrored) view and lower left p4 (SNSBBSPG 2020 XCIV-0487) for step-length of "age groups" definition in lingual and buccal views. WS 1, unworn: no wear can be observed, deciduous dentition in use; WS 2, slightly worn: first occlusal contact; WS 3, worn: para/metaflexus/id is closing or just closed; WS 4, medium worn: mesoflexus/id is closing or just closed; WS 5, deeply worn: hypoflexus/id is near to closing; WS 6, heavily worn: hypoflexus/id is closed. Occlusal pattern of lower right p4: WS 1, 3, 5 and 6: line drawings not based on specific specimens, WS 2: GPIT/MA/10745, WS 4: GPIT/MA/09896 (mirrored). WS 1–6 not to scale.
