Diagnosis
ReferenceDiagnosis
W. D. Matthew and H. J. Cook 1909
Gigantic camels with dentition I 1/3, C1/1, P3-2/3-2, M3/3, the second premolar absent in both jaws, the first retarded or absent, the reduction of the posterior premolars intermediate between Procamelus and Camelus. Upper molars with promineμt external ribs and styles, as in Auchenia Limbs and feet moderately elongate and very massive, large in proportion to size of skull.
M. R. Voorhies and R. G. Corner 1986(Modified after Matthew and Cook (1909), Webb (1965), and especially, Harrison (1979).) Large camelines with dental formula 1· 1·3·3/3·1·3· 3; 13/large, caniniform; C/C large, rounded; Plll pres- ent but not always erupted in females; P3/ variably reduced, seldom with complete internal crescent; mo- lars moderately low crowned (much less hypsodont than in Camelus, Gigantocamelus, or Camelops); ce- ment lacking in molar fossettes; antero-external stylids ("llama buttresses") lacking on lower molars; distal limb elements not foreshortened as in Gigantocamelus; proximal phalanges with posterolateral edges raised but attachment area of suspensory ligaments not oc- cupying more than one-half of posterior surface as in Camelops.
