Diagnosis
| Reference | Diagnosis | |
|---|---|---|
| L. M. Chiappe et al. 2002 | Cervical centra strongly compressed laterally, lacking pneumatic foramina; cranialmost thoracic vertebrae strongly compressed; fused ilium and ischium; pillarlike deltopectoral crest of humerus; supracetabular crest developed only in the cranial portion of acetabulum; subtriangular cross section of pubis; two cnemial crests in tibiotarsus; medial indentation of ascending process with deeply excavated base; ascending process arises from medial margin of astragalar condyle instead of from lateral margin. |
