Diagnosis
| Reference | Diagnosis | |
|---|---|---|
| E. Gorscak et al. 2017 | Shingopana songwensis is a titanosaurian sauropod diagnosed by the following autapomorphy: middle-to-posterior cervical vertebrae with divided spinoprezygapophyseal lamina (forming a spinoprezygapophyseal lamina fossa) near the base of an expanded neural spine. Several morphological characters support Shingopana songwensis within titanosauriforms (e.g., Wilson, 2002; D'Emic, 2012; Mannion et al., 2013): (1) camellate internal texturing of cervical vertebrae; (2) low infrazygapophyseal region of posterior cervical vertebra; (3) elongated cervical rib shaft extending past succeeding vertebra; (4) proximal region of dorsal ribs with pneumatic foramina; (5) squared proximolateral corner of humerus; and (6) undivided radial condyle of humerus. Characters that support lithostrotian affinities include (1) undivided and shallow lateral fossa of the cervical centrum; (2) absence of a ventral midline keel on the cervical centra; (3) elongated (i.e., not subcircular) cervical parapophysis; and (4) mediolateral narrowing of neural canal of the cervical vertebrae (Wilson, 2002; D'Emic, 2012; Mannion et al., 2013). The bulbous expansion of the cervical vertebral neural spine suggests affinities with the Late Cretaceous South American titanosaurians Bonitasaura salgadoi (Gallina and Apesteguía, 2015), Overosaurus paradasorum (Coria et al., 2013), and Trigonosaurus pricei (Campos et al., 2005), and anterior dorsal ribs with anterior and posterior proximal flanges suggest affinities with Overosaurus. |
