Fig. 14 in First Crania and Assessment of Species Boundaries in Nimbadon (Marsupialia: Diprotodontidae) from the Middle Miocene of Australia

Fig. 14. Morphological variation in the RP3 of Nimbadon lavarackorum from AL90 site. Specimens used are as follows: A, QM F53653; B, QM F50696; C, QM F50695; D, QM F53784; E, QM F30833; F, QM F53659; G, QM F50694; H, QM F53643; I, QM F42677; J, QM F50745; K, QM F53654; L, QM F30781. Specimens A, E, J, K and L are mirror images of left P3's to facilitate comparison. 1, weak buccal emargination between anterior and posterior moieties compared with 2, strong emargination; 3, short parastylar shelf as opposed to 4, elongate; 5, weak anterolingual cingulum compared with 6, well developed; 7, hypocone absent compared to 8, small or 9, moderately developed; 10, anterior hypocone crest present; 11, protocone large and bulbous as opposed to 12, small, or 13, narrow and lingually compressed; 14, parastyle small compared with 15, well developed; 16, parastyle hooked; 17, deep transverse valley separating parastyle from parametacone base, compared with 18, shallow valley or 19, valley absent entirely; 20, anterolingual parametacone crest terminates at valley between protocone and parametacone bases as opposed to 21, meets the lingual cingulum or 22, meets a buccal protocone crest; 23, posterobuccal cingulum absent compared to 24, well developed; 25, mesostyle present; 26, weak anterolingual emargination between pas and protocone compared with 27, strong emargination.
