English: Skeletal reconstruction of the giant Argentine titanosaur Argentinosaurus. The holotype, MCF-PVPH 1,^[1] consists of six described dorsal vertebrae, another undescribed dorsal vertebra,^[2] five sacral vertebrae, an ilium, a pubis, and a fibula.^[1] The pubis was not figured, and only the dorsal vertebrae are figured in lateral view.^[3] Two tentatively referred femora, the partial MLP-DP 16-VIII-21-3 and an unnumbered, crushed specimen, are also known.^[1] The pubis, ilium, sacrum, and fibula were drawn based on Carpenter's skeletal as well as Patagotitan.^[4] Unfigured holotypic material is shown in light gray.

Missing regions were restored after Patagotitan (overall proportions),^[5][6] Futalgonkosaurus (missing hip bone outlines),^[7] Notocolossus (feet),^[8] and Tapuiasaurus (skull).^[9] Measurements from Paul's review of giant titanosaurs were used to help with the scaling.^[10] The human silhouette is from File:Silhouette of man standing and facing forward.svg (CC0). The total length of the sauropod is about 35 metres (115 ft) in this reconstruction, although this should be treated as tentative, as should any attempted reconstruction of this taxon, due to the fragmentary nature of the remains.
