J. Velez-Juarbe and D. P. Domning 2015 | Dugongine of medium body size (2–3 m; Sarko et al., 2010); differs from other dugongines by displaying the fol- lowing unique combination of plesiomorphic and derived charac- ters: nasal process of premaxilla tapering but thickened (c. 6[1]), shared with Kutchisiren cylindrica, Rytiodus capgrandi, and Bharatisiren kachchhensis; supraorbital process of frontal dorso- ventrally thin (<2 cm) and well developed, with recurved, bluntly pointed posterolateral corner (c. 36[0]), shared with Bharatisiren kachchhensis and Dioplotherium sp. (ECOCHM 2491); ventral rim of orbit not overhanging the lateral surface of the jugal (c. 90[0]), shared with Corystosiren varguezi; pterygoid fossa tall [c. 102(1)], shared with Crenatosiren olseni, Rytiodus heali, and Bharatisiren spp.; and tusks large (longer than half the length of the premaxillary symphysis) (c. 140[2]), lozenge- or kite-shaped in cross-section (c. 141[2]), and with enamel confined to the medial side (c. 142[1]). Displays the following apomor- phies: lacrimals with thin (<5 mm), elongated (»20 mm) dorsal process that is wedged between the premaxilla and frontal, and osteosclerotic but minimally pachyostotic ribs and vertebrae. |
