Narambuenatitan palomoi

Reptilia - Titanosauridae

Taxonomy
Narambuenatitan palomoi was named by Filippi et al. (2011). Its type specimen is MAU−Pv−N−425, a partial skeleton (left premaxilla and maxilla; braincase; left and right quadrates; anterior cervical vertebra; cervical rib fragments; poste− rior dorsal vertebra; three d), and it is a 3D body fossil. Its type locality is Puesto Narambuena, which is in a Campanian/Campanian pond sandstone/mudstone in the Anacleto Formation of Argentina.

If no rank is listed, the taxon is considered an unranked clade in modern classifications. Ranks may be repeated or presented in the wrong order because authors working on different parts of the classification may disagree about how to rank taxa.

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.
