Diagnosis
| Reference | Diagnosis | |
|---|---|---|
| S. J. Nesbitt et al. 2023 | The holotype of Mambachiton fiandohana differs from all other archosauriforms by the presence of the following combination of character states (asterisks indicate autapomorphies): *small tuber present at the dorsal margin of the prezygadiapophyseal lamina on the lateral side of the prezygapophysis in the cervical vertebrae; epipophyses absent on the dorsal surface of the postzygapophysis; laterally expanded dorsal portion of the neural spine; tapering anterior
process of the cervical osteoderms articulating with a distinct groove on the ventral surface of the preceding osteoderm; smooth, unsculptured osteoderms; *high number of osteoderms per cervical vertebra (five to eight, depending on position); staggered arrangement of osteoderms across the midline. Potential further diagnostic character states for this new taxon discernable from the referred material include: neural spines of the trunk vertebrae and first sacral vertebra laterally expanded dorsally; weakly developed hyposphene–hypantrum articulations between the trunk vertebrae; lateral articulation surface of sacral rib anteriorly and posteriorly constricted, resulting in an ‘I’-shape; coracoids with short postglenoid processes; distal end of the scapula expands anteroposteriorly more than the proximal end; rugose tuber occurs just distal to the glenoid of the scapula; ilium with notch on the articular surface for reception of the ischium. |
