Description
So far, only individual fragments of his skeleton have been found; therefore, estimates of its length range from 22 to 35 m (reconstruction at the Carmen Funes Museum is 39.7 m in length), and weights from 60 to 108 tons [2] [3] [4] [5] . Among the fragments found is a vertebra with a height of 159 cm. Fossil remains were found in Argentina by local paleontologists José Fernando Bonaparte and Rodolfo Coria and described as a new species Argentinosaurus huinculensis in 1993 [6] ; the found remains belong to the middle of the Cretaceous period ( 99.6–89.8 million years ago [7] ). Perhaps even larger were the Bruhatkayosaurus , Puertasaurus , Breviparop , Amphicelia , Diplodocus , and Super Saur .
Systematics
The exact systematic position of the Argentinosaurus remains unclear. For example, in 2005: Christina Curry Rogers assigned it to the subfamily Opisthocoelicaudiinae , L. Salgado and R. Koria - to the Titanosauridae family, and Sebastian Apestegia - to the Andesauridae family. After the work of 2013, R. Koria and colleagues put the genus in the clade Lithostrotia [7] .
