Diagnosis
| Reference | Diagnosis | |
|---|---|---|
| D. R. Prothero 1996 | Large camel (P2-M3 length = 70.0 mm), distinguished from contemporary P. primaevus by its larger size, and by the presence of metastylids on the lower molars. Distinguished from all other Eocene/Oligocene camels by its advanced features, including lower molar metastylids, strong P3 lingual cingulum, more spatulate lower incisors, and shortened PI. Distinguished from Miocene camels by its primitive skull proportions and by its brachydont teeth which are small relative to the skull size (Table 2). | |
| K. Marriott et al. 2022 | Same as for genus. [(modified from Honey et al., 1998, p. 447): A double-rooted Pl, unreduced P2-4 compared to Oxydactylus; weaker P3 internal crescent compared to Oxydactylus. Brachydont cheek teeth, with large ribs and styles on upper molars, approximately 1/3 the size ofthe paracone or metacone. Intercolumnar tubercles on Ml-3 and on m3. The rostrum and mandibular symphysis have a distinctive ventral deflection. Shallow maxillary fossa. Palatine notch extending to middle of M2. Inflated auditory bulla. Metacarpals slender and shorter than length ofskull, with metatarsals longer than metacarpals. Distal articular surfaces ofproximal phalanges unexpanded dorsally.] |
