Summary

[edit]
Description
English: A size comparison of three femurs (thigh bones) that were assigned to the sauropod dinosaur genus Antarctosaurus by Friedrich von Huene in 1929.
• MACN 6904 is part of the type specimen of Antarctosaurus wichmannianus and measures 1.39 meters long. [1]
• FNMH P13019 was also assigned to Antarctosaurus wichmannianus by Huene but later authors think it belongs to either Argyrosaurus or an indeterminate titanosaur.[2] It measures 1.85 meters long.[1]
• MLP 23-316 is part of the type specimen of Antarctosaurus giganteus and is one of the longest femurs known, measuring 2.35 meters in length.[1] Huene tentatively referred A.giganteus to the genus Antarctosaurus and other authors doubt the referral with some thinking it belongs to an as yet unnamed genus. [3] [4]
• The femurs are based on illustrations in Huene 1929. [1]
• Humans scaled to 170 cm and 160 cm respectively.
