Diagnosis
| Reference | Diagnosis | |
|---|---|---|
| L. G. Barnes 2013 | A genus of the subfamily Paleoparadoxiinae differing from Archaeoparadoxia and Paleoparadoxia by having larger body size and by having relatively larger cranium that is more massive and wider transversely, with larger oral cavity; larger dorsal naris; transversely wider nasal bones; larger and more dorsally placed orbits; margin of orbit extending farther laterally because of flared ventral edge of jugal at anterior end of zygomatic arch; dorsoventrally deeper jugal ventral to orbit; supraorbital process of frontal larger, wider, thicker, more elevated dorsally, and extending farther laterally; several nutrient foramina present on dorsal surface of supraorbital process; dorsal surface of cranium between supraorbital processes depressed rather than elevated; zygomatic arches bowed more laterally rather than nearly parallel-sided; more extensive area of parietal bones that form lateral wall of braincase; proportionally larger temporal fossae; shorter, transversely wider, and much more massive paroccipital processes; M2 and m2 crowns having cingula extended crown- ward to form additional cuspules and larger occlusal surfaces; first rib less curved; three pairs rather than four pairs of mesosterna; more massive limb bones (e.g., distal end of humerus nearly twice the absolute width of that of A. weltoni and approximately 1.5 times the width of that of P. tabatai); humerus with relatively larger pectoralis major tuberosity; tibia/ fibula distal articulation enlarged, triangular and tapered proximally, differing further from Archaeoparadoxia by having by having transverse processes on thoracic vertebrae more inclined dorsolaterally; lateral projection of proximal end of fifth metacarpal; astragalar facet on distal end of tibia more tilted proximally; differing further from Paleoparadoxia (based on neotype of P. tabatai) by having deeper sulcus in dorsal surface of vomer in floor of dorsal naris; wider rostrum; absolutely and relatively larger infraorbital foramen; fossa present on anterior side of paroccipital process; anterior part of palate nearly flat rather than transversely arched; wider cleft at posterior end of palate between pterygoid hamulae, relatively and absolutely larger glenoid fossa; ontogenetically later eruption of M3 and m3; mandible with more ventrally bent anterior end; deeper and transversely wider fossa in oral cavity dorsal to mandibular symphysis; mandibular condyle positioned more dorsally relative to dorsal margin of horizontal ramus; coronoid crest more reclined posteriorly; mandibular foramen larger and positioned more dorsally relative to dorsal margin of horizontal ramus; proportionally larger p1 (‘‘snagging tooth’’); proportionally larger p2; and astragalar facet on distal end of tibia more tilted proximally. |
