Diagnosis
ReferenceDiagnosis
G. S. Paul 2008Adults large. Overall lightly constructed. Premaxillary tip to anterior orbital rim/latter to paraoccipital process tip length ratio ~1.6 via elongation of posterior nasal, maxillary process of premaxilla and maxilla; dentary pre-coronoid process length/minimum depth ratio under 5. Premaxilla and nasal *form large crest. Premaxilla projects well below level of tooth rows, maxillary process is moderately deep. Dorsal apex of maxilla set posteriorly. Antorbital fossa small. Lacrimal long, contacts nasal. Accessory palpebral absent. Lateral temporal fenestra moderate in size. Posterior portion of jugal long. Quadratojugal tall. Quadrate short, transversely narrow, shaft straight, lateral foramen set high, dorso-posterior buttress absent. Diastema short. Tooth positions *26 in maxilla, *24 in dentary, incipient 3rd row in many positions. Scapula blade narrow and constricted at middle of blade, base rather narrow, acromion process placed rather dorsally. Deltopectoral crest of humerus distally placed, modest in size. Manus narrow, pollex spike and other unguals moderate in size. Anterior prong of ilium *robust, *strongly arced ventrally, main body deep. Prepubic process of pubis moderate in depth.
