SciNews has a story about the discovery of yet another titanosaur from Argentina.  This one is called Bustingorrytitan shiva and it lived about 95 million years ago in what is now Patagonia during the Late Cretaceous Period.  This particular discovery consists of a fairly complete specimen and three other partial skeletons.  Read more about it in a paper in the journal Acta Palaeontologica Polonica.

“Five species, four of which inhabited Patagonia, would have reached body masses of 50 tons or more: Patagotitan mayorum, Argentinosaurus huinculensis, Notocolossus gonzalezparejasi, not from Patagonia but from the Neuquén Basin, Puertasaurus reuili, and Dreadnoughtus schrani.”

“However, only one of these, Dreadnoughtus schrani, preserves a humerus and femur from a single individual, with the possibility to estimate the body mass by means of scaling equations, which are robust predictors of body mass in quadrupedal tetrapods.”

Bustingorrytitan shiva was a member of Lithostrotia, a large group of titanosaur sauropods that lived during the Cretaceous period.
