[29] The dorsal ribs were tubular and cylindrical in shape, in contrast with other titanosaurs. [53] The authors concluded with its giant size, Argentinosaurus reached a functional limit. Titanosaur Fossil in Argentina May Belong to the Largest Land Animal Ever [7], Argentinosaurus likely possessed 10 dorsal vertebrae, like other titanosaurs. Did Scientists Just Unveil the Biggest Dinosaur of All Time? Mazzetta and colleagues used regression equations to estimate its original length at 2.557 metres (8.39ft), which is similar to the length of the other femur, and later in 2019 Paul gave a similar estimate of 2.575 metres (8.45ft). The optimal gait found by the algorithms was close to a pace (forelimb and hind limb on the same side of the body move simultaneously). Both specimens belonged to individuals equivalent in size to the holotype individual. Titanosaurus vs. T-Rex! : r/Dinosaurs - Reddit [45], Overlooking the naming of Titanosauria, Paul Upchurch in 1995 named the clade Titanosauroidea, to include Opisthocoelicaudia and the more derived Titanosauridae (Malawisaurus, Alamosaurus and Saltasaurus). [2] In 2019, Paul estimated the total length of the dorsal vertebral column at 447 centimetres (176in) and the width of the pelvis at 0.6 times the combined length of the dorsal and sacral vertebral column. The impressions showed that titanosaurs were covered in a mosaic armour of small bead-like scales. As these articulations were also present in the titanosaurids Andesaurus and Epachthosaurus, Bonaparte and Coria proposed a separate family for the three genera, the Andesauridae.

Using the matrix of Wilson (2002), following the additions of a few cranial characters and Diamantinasaurus, Tangvayosaurus and Phuwiangosaurus, remained the same as originally found by Wilson but with Diamantinasaurus sister to Saltasauridae and the other two genera as basal titanosaurs outside Lithostrotia, since Titanosauria, while undefined, was labelled to include all taxa closer to Saltasaurus than Euhelopus.
