• Lingwulong shenqi (violet): A very large dicraeosaurid from the Jurassic of China. Drawn and scaled based on the skeletal diagram in Xu et. al. (2018),^[1] with the skull based on that of Bajadasaurus in Gallina et. al. (2019).^[2]
• Suuwassea emilieae (blue): A large dicraeosaurid from the Jurassic of North America. Drawn and scaled based on a skeletal diagram by myself.
• Amargasaurus cazaui (green): An average-sized dicraeosaur with elaborate neck spines from the Cretaceous of South America. The presacral column was drawn primarily following Windholz et al. (2022),^[3] with additional information from Salgado & Bonaparte (1991)^[4] and Schwarz et al. (2007).^[5] The limbs were based on the figures and measurements of Salgado & Bonaparte (1991).^[4] The skull is based on that of Bajadasaurus in Gallina et. al. (2019)^[2] while the tail was restored based on Dicraeosaurus.
• Dicraeosaurus sattleri (red) and D. hansemanni (brown): Two large dicraeosaurs from the Jurassic of Africa. Drawn and scaled based on skeletal diagrams by myself (D. sattleri & D. hansemanni).
• Brachytrachelopan mesai (orange): A small dicraeosaurid from South America that lived during the Jurassic. Drawn and scaled based on a skeletal diagram by myself.
• All lengths are within one meter of those given by Paul (2016),^[6] with the exception of Lingwulong, which was unknown to him at the time.
