Diagnosis
ReferenceDiagnosis
L. S. Filippi et al. 2011Titanosaur characterized by the following autapomorphies: (1) great participation of the frontal to the rostral border of the supratemporal fossa, (2) absence of ornamentation on the supraorbital or lateral borders of the frontal, (3) presence of a lamina joining each parietal crest with the rostral surface of the supratemporal, (4) pleurocoel dorsal border defined by a prominent convex bony edge in posterior dorsal vertebrae, (5) distal enlargement of the prespinal lamina in posterior dorsal vertebrae, matching with a lateral enlarged of the neural spine, (6) kidney−shaped prezygapophysis in posterior dorsal vertebrae, (7) presence of numerous pneumatic cavities located posterior to the centroparapophyseal lamina and centrodiapophyseal lamina in posterior dorsal vertebrae, (8) middle−anterior caudal vertebrae with the anterodorsal border of the neural spine anteriorly inclined, (9) middle caudal vertebra with a slender prezygapophysis and neural arch.
