How this 3D skeleton was made
This 3D model is a reconstruction. Most bone shapes (152 of 161) are borrowed from close relatives and fitted to this species' size and body proportions. The bone shapes are not the actual shapes of this species' fossils. 9 are estimated.

- 3D Skeleton: Borrowed bone shapes from the template 'Mnyamawamtuka' (S5). Since there are no direct measurements of body part lengths for this species, the size was determined from a 2250 mm femur of one specimen (MCF PVPH-1) in the table of Benson et al. (2018), keeping the proportions of other body parts from the template. The shapes of individual bones are not from this species, but from the template species. Template skeleton source: 3D Skeleton: Created on this site. Known bone shapes were traced from outlines of bone photos of the holotype RRBP 05834, scaled to the measurement tables and figure scale bars in the same paper (Gorscak & O'Connor 2019 PLOS ONE, CC BY 4.0). Missing neck, head, torso, and tail lengths were estimated from proportions of the 3D mounted skeleton of the related Rapetosaurus (Dempsey et al. 2025, CC BY 4.0). Pose (2026-09-30): Approximate angles visually read from bone orientations in Figure 10 (calculated gait motion frame for Argentinosaurus, 0.000 s) of Sellers et al. 2013 PLOS ONE (CC BY) (hind legs: front leg thigh 18 degrees forward, shin 24 degrees back; back leg thigh 6 degrees back, shin 39 degrees back / forelegs: planted leg upper arm 33 degrees back, forearm 28 degrees forward; lifted swinging leg upper arm 39 degrees back, forearm 3 degrees back). Orientations of instep and hand are estimated. All sauropods were assigned this walking style (no species-by-species calculations exist). Rather than a walking diagram of this species itself, bone orientations from a relative with a similar gait were applied. The neck was turned slightly to the side, and the tail curved sideways (the degree of turn is estimated; the figure shows only a side view).
- Known bones: Sauropodomorph bone table from Cashmore et al. (2020) (skeletal completeness 8%; no records on hand of which specific bones are missing). Bones with even partial remains are colored as "discovered." Vertebrae are given as proportions per section (neck, back, hips, tail), so bones in each section share the same color. Because there are no individual bone records, gray = unknown.
