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.

) and from the same stratigraphical level. No repeated elements were found. According to their position in the field, they represent a single individual that was lying with its left side down. The two fragmentary posterior cervical vertebrae together with several pairs of cervical ribs were found articulated, with the cervical ribs overlapping at least two consecutive ones. Their position in the field suggests the neck was dorsiflexed, which indicates the skeleton has undergone at least a slightly post-mortem exposure prior its final burial. The same pattern was observed in the recovered anterior caudal series. The high degree of articulation, together with the presence of both large complete bones and small and delicate elements, also suggests the skeleton has undergone little transport.

Several theropod and crocodylomorph teeth have been recovered from the area where both femora were found. The presence of these teeth around this portion of the skeleton suggests that small theropod dinosaurs and crocodylomorphs have fed on the carcass. This pattern has also been reported elsewhere, where teeth of carnivorous dinosaurs are found near the sacral region of articulated or semi-articulated sauropods (

According to the preserved portions, the internal bony tissue (camellae) of the centra is composed of subcentimetrical coels circumscribed by thin lamellae. Both vertebrae have the left cervical ribs attached to their centra. The capitulum and tuberculum are thin sheets of bone which are anteroposteriorly wide. However, their contact with the transverse processes is not clear. The tuberculum is internally reinforced by a columnar ridge that extends from the base of the capitulum until the tuberculum. The anterior end of the cervical ribs is shorter than the posterior one and tapers to a point. The posterior end is long and slender, formed by a thin dorsoventrally convex sheet of bone that gradually becomes oval in cross section toward the end.

On both vertebrae the parapophyses are badly damaged and therefore cannot be properly described. The diapophyses are blade-like projections and lay under the level of the prezygapophyses. On the posterior margin of the diapophyses there is a small sheet of bone that projects posteriorly. The most striking feature of these vertebrae is the strong development of the posterior centrodiapophyseal lamina, which is stouter than the postzygodiapophsyeal lamina. Although not completely preserved on both centra, the posterior centrodiapophyseal lamina seems to extend until the posterior margin of the centrum. The postzygodiapophsyeal lamina is thin, well-developed, and extends until the anterior margin of the postzygapophysis. This region is only preserved in the anteriormost cervical vertebra, which is broken and levered forward and upward by the forward displacement of the proceeding cervical vertebra (

Only fragmentary dorsal vertebrae are preserved. A fragmentary neural arch is preserved, comprising a partial neural spine, the right diapophysis, and the right prezygapophysis. According to the height of the neural spine and its shape, this dorsal vertebra is regarded as a middle dorsal vertebra. The neural spine is tall and has an acute triangular shape in anterior view and is anteroporsteriorly short. The diapophysis is robust, short, and directed laterally. The spinodiapophyseal lamina is stout and well developed. The prezygapophysis is broken and seems to be shifted to a more medial position because its articular facet is unusually aligned to the sagittal plane (

In the anterior face of the neural arch there are three fossae that widen into large internal chambers. Between these fossae, on the anterior portion of the neural arch, there are two diagonal shallow ridges that cross each other near their base. Some isolated transverse processes also have spongy bony tissue.

The four remaining anterior caudal vertebrae are well preserved except for the last two vertebrae which lack the transverse processes. The centra are higher than wide and become progressively longer toward the posterior caudal vertebrae. In posterior view, the posterior ends are roughly hexagonal in shape. The articular area for the haemal arches is well-developed, forming a protuberance with a shallow pit at the ventroposterior margin of the centra. The ventral faces are slightly concave anteroposteriorly and laterally compressed, with incipient lateroventral ridges. The transverse processes are robust and strongly directed backward. The neural arches are located on the anterior half of the centra, reaching the anterior margin of the centra of the last two preserved anterior caudal vertebrae. The prezygapophyses become straight and relatively long, with moderately developed articular facets. The spinoprezygapophyseal laminae are well-developed, forming a deep fossa at the base of the neural spine. The postzygapophyses are robust, with concave articular facets and stout spinopostzygapophyseal laminae. The neural spines are laterally compressed at their base and laterally expanded at their distal end. They are directed forward, mainly in the last two anterior caudal vertebrae. The prespinal and postspinal laminae are incipiently developed (

C). It is a blade-like element with the proximal end directed anteriorly. The posterior portion is damaged and exposes the internal spongy bony tissue and, because of that, it is not possible to determine the shape of the cross section. Other fragments regarded as anterior dorsal ribs have the cross section of the proximal end triangular in shape. The mid-dorsal ribs have shafts with subtriangular cross sections that become blade-like or elliptical toward their distal ends. A mid-thoracic rib has a marked depression between the capitulum and the tuberculum in medial view. The proximal portion of the shaft is D-shaped in cross section with sharp well-developed ridges on both the antero and posterolateral margins (

The acetabular area is partially preserved, corresponding to a gently concave area between the pubic and iliac articulations, where the bone is thinner than the posterodorsal margin. According to the preserved portion of the distal process, it seems to be relatively long and its thickness decreases from the dorsal margin to the ventral one. The distal process is twisted medially which indicates that when in articulation with its counterpart they should have met in a horizontal plane (

A1–4), the left one is complete and well preserved, the right one lacks the distal end and part of the shaft. Although large (1.55 m in length), the femur is a relatively slender element. It is straight and strongly compressed anteroposteriorly, so that the shaft has an elliptical shape in cross section. The femoral head is well developed and extends well above the level of the greater trochanter and medially. The femoral head is not aligned with the great trochanter, so that in dorsal view it is slightly directed backward, forming a shallow concave area between both the great trochanter and the femoral head. A lateral bulge is present right under the great trochanter; it is gently convex and extends over the third proximal portion of the shaft. The fourth trochanter is relatively well-developed and located on the posteromedial portion of the shaft at its third upper part. The distal articulation is well-developed and extends from the posterior to the anterior margin of the femur so that in both posterior and anterior view there is a concave area between the tibal and fibular condyles. The same holds true for the distal margin. The tibial condyle is more developed than the fibular one in the way the posterior portion of the former is more developed posteriorly. However, the fibular condyle is stouter and bifurcates into two condyles. The internal (medial) one is more developed and slightly directed laterally. The lateral fibular condyle is less developed and forms part of the lateral corner of the distal end of the femur (
