Diagnosis
| Reference | Diagnosis | |
|---|---|---|
| M. J. Wedel et al. 2000 | Cervical centra extremely elongate; centrum length more than five times posterior centrum height. Differs from all other sauropods in possessing well-defined centroparapophyseal laminae that extend to the posterior ends of the centra, diapophyses located approximately one third of centrum length behind anterior condyles, deeply excavated neural spines which are perforate in anterior cer vicals, and hypertrophied central pneumatic fossae that extend posteriorly to the cotyles. Neural spines occupy anterior nine-tenths of centra and are not bifurcate. Cervical ribs are slender and elongated, with long, robust anterior processes that extend nearly to anterior condyles; total length of each cervical rib equals or exceeds 3 centrum-lengths. | |
| M. J. Wedel et al. 2000 | Cervical centra extremely elongate; EI of mid-cervicals greater than 5. Differs from all other sauropods in possessing well-defined centroparapophyseal laminae that extend to the posterior ends of the centra, diapophyses located approximately one third of centrum length behind anterior condyles, deeply excavated neural spines which are perforate in anterior cervicals, and hypertrophied central pneumatic fossae that extend posteriorly to the cotyles. The internal structure is entirely composed of pneumatic camellae separated by bony septa ranging in thickness from less than 1 mm to approximately 3 mm. Total length of each cervical rib equals or exceeds three centrum-lengths. | |
| M. D. D'Emic 2013 | Extreme elongation of the middle cervical vertebrae (length/posterior centrum height > 6), middle cervical vertebrae with posterior expansion of the pneumatic fossa to the cotyle, neural spines perforated in middle cervical vertebrae, top of neural spine with broad midline ridge flanked by small fossae at its anterior and posterior ends, middle and posterior dorsal neural spines that taper distally, anterior caudal vertebral centra roughly square in cross section, anterior caudal vertebrae with divergent spinoprezygapophyseal laminae (angle greater than 50◦) forming wide spinoprezygapophyseal fossae, scapula with two processes at the base of the ventral edge of the blade, humerus gracile, length/midshaft width > 7.5. |
