Diagnosis
| Reference | Diagnosis | |
|---|---|---|
| M. E. Simón and L. Salgado 2023 | Simón & Salgado (2023): Bustingorrytitan shiva gen. et sp. nov. is characterized by the following autapomorphies (those indicated by an asterisk are those autapomorphies recovered by the phylogenetic analysis): *ventral surface of the cervical centrum concave transversely; *pleurocoels absent in cervical centrum; *slightly opisthocoelous posterior dorsal vertebrae; *pleurocoel with angular dorsal margin in middle to posterior dorsal vertebrae; *dorsal margin of pleurocoels at the level of or higher than the dorsal margin of the centrum in posterior dorsal vertebrae; *neural spine of middle to posterior dorsal vertebrae with subparallel lateral margins in anterior posterior view; posterior dorsal vertebrae with very developed anterior (aspdl) and posterior (pspdl) spinodiapophyseal laminae, limiting a deep, vertical, socket-like fossa; posterior dorsal neural arches with forked centropostzygapophyseal laminae (cpol); *prespinal lamina (prsl) rough and wide, extended through almost all the neural spine, in dorsal vertebrae; *presence of a single lamina (the single tpol) supporting the hyposphene or postzygapophysis from below in mid and posterior dorsal vertebrae; *absence of lateral spinopostzygapophyseal lamina (lspol) in middle and posterior dorsal neural spine; *height of neural arch below the postzygapophyses (pedicel) subequal to or greater than height of centrum in mid and posterior dorsal vertebrae; *solid, not pneumatized, neural arches in anterior caudal vertebrae; *anterior caudal vertebrae with spinoprezygapophyseal laminae ventral and medially placed, usually described as bifurcated prsl; *anterior caudal vertebrae with spol poorly developed causing the articular facet of the postzygapophysis to project slightly from the midline; hyposphene in anterior caudal vertebrae; *middle caudal centra with flat ventral margin; *prezygapophyses of mid caudal vertebrae anterodorsally oriented (around 45°); *well developed acromion process of scapula; *acromial process
placed at nearly midpoint of the scapular body; *scapular acromion at least 1/2 of scapular length; *glenoid scapular orientated relatively flat or laterally facing; *dorsal margin of the coracoid lies, in lateral view, below the level of the scapular proximal expansion and separated from the latter by a V-shaped notch; *humerus gracile (RI less than 0.27); *radial condyle of humerus divided on anterior face by a notch; humerus with deltopectoral crest strongly expanded distally; *ulnar olecranon process rudimentary; *transverse axis of the distal condyle of metacarpal I beveled approximately 20° respect to axis of shaft; *proximal symphysis of the pubis forming a marked ventromedially directed process; femur with a low longitudinal crest on the lateromedial half of the anterior face, bifurcated in two lesser crests, each of which is directed to one of the condyles; *distal breadth of tibia approximately 125% its midshaft breadth; *minimum transverse shaft diameters of metatarsals III and IV subequal to that of metatarsals I or II; *metatarsal V shorter than metatarsal IV. |
