Arrudatitan maximus
Taxonomy
Aeolosaurus maximus was named by Santucci and Arruda-Campos (2011). Its type specimen is MPMA 12-0001-97, a partial skeleton, and it is a 3D body fossil. Its type locality is Santa Irene farm, which is in a Campanian/Maastrichtian terrestrial sandstone in the Adamantina Formation of Brazil.
It was recombined as Arrudatitan maximus by Silva Junior et al. (2022) and Navarro et al. (2022).

| R. M. Santucci and A. C. d. Arruda-Campos 2011 | Titanosaur characterized by the following unique association of characteristics: well-developed posterior protuberance below the articular area on the anterior and middle haemal arches and lateral bulge on the distal portion of the articular process of the mid-posterior haemal arches. An additional set of ambiguous synapomorphies includes: presence of posterior centrodiapophyseal lamina (pcdl) at least 50% thicker than the postzygodiapophyseal lamina (podl) in posterior cervical vertebrae; posterior dorsal vertebrae with intrapostzygapophyseal lamina and an oblique anterior centropostzygapophyseal lamina (acpol) which bifurcates from the proximal portion of the centropostzygapophyseal lamina (acpol); mid-thoracic ribs bearing well-developed anterior and posterior crests with a D-shaped cross section. These features are considered ambiguous because they cannot be assessed in other Aeolosaurus species so far, and may correspond to a set of synapomorphies of Aeolosaurus or even Aeolosaurini. |
