Diagnosis
| Reference | Diagnosis | |
|---|---|---|
| S. A. Hocknull et al. 2009 | Wintonotitan wattsi gen. et sp. nov. is characterised by the unique association of the following features. Dorsal vertebrae possessing camellate pneumatic cavities; deep eye-shaped pleurocoels; prespinal and postspinal laminae extending along entire length of neural spine; incipient spinoprezygopophyseal lamina (autapomorphic). Dorsal ribs with pneumatic cavities along 1/3 of proximal end; large and plank-like. Caudal vertebrae number approximately 35; all with solid internal bone structure; anterior and middle caudal vertebrae amphiplatyan; anterior caudals with straight neural spines above cranial half of vertebra; posterior caudals incipiently biconvex and cylindrical (autapomorphic). Scapula long with broad acromial blade; ventromedial process present; mid-scapular blade ridge present; scapular-coracoid articular connection thin medio-laterally; distinct acromial ridge. Humerus gracile with divided distal condyles; deltopectoral crest low and narrow, terminating proximal of mid-shaft. Ulna long and gracile with broad proximal end and rounded distal articular end. Radii long and gracile; expanded sub-equally at proximal and distal ends. Metacarpals long and robust, distal condyles undivided and flat, missing phalangeal articular facets. Mc I longest, then Mc II, Mc III, Mc IV and Mc V. Preacetabular blade of ilium projecting antero-laterally from sacral axis; iliac blade with pneumatic cavities. Ischium broad and flat with robust iliac peduncle and thin ischial blade with rounded distal margin. |
