    Summary

    Description
    English: Size comparison of living and extinct gliding reptiles compared to a human hand.
    • Scale of Coelurosauravus is based on a skeleton diagram pictured in fig 15 of "The postcranial skeleton of the gliding reptile Coelurosauravus elivensis Piveteau, 1926 (Diapsida, Weigeltisauridae) from the late Permian of Madagascar" by Valentin Buffa ,Eberhard Frey,J.-Sébastien Steyer & Michel Laurin.
    • Silhouette of Weigeltisaurus based on a figure in "Osteology, relationships and functional morphology of Weigeltisaurus jaekeli (Diapsida, Weigeltisauridae) based on a complete skeleton from the Upper Permian Kupferschiefer of Germany" by Adam C. Pritchard​, Hans-Dieter Sues, Diane Scott, Robert R. Reisz, which is under a CC BY license. As this figure did not have a scale, I scaled it to the 6 cm skull length given in ""Substantiation of Validity of the Late Permian Genus Weigeltisaurus Kuhn, 1939 (Reptilia, Weigeltisauridae" by Bulanov, V.V.; Sennikov, A.G.
    • Silhouette of Draco volans is based on a figure in "Influence of posture during gliding flight in the flying lizard Draco volans" by Valentin Buffa, William Salaün and Paola Cinnella, released under a CC-BY 4.0 license
    • Silhouette and scale of Mecistotrachelos based on information in " "A new gliding tetrapod (Diapsida: ?Archosauromorpha) from the Upper Triassic (Carnian) of Virginia" by Fraser, N.C.; Olsen, P.E.; Dooley, A.C. Jr.; Ryan, T.R.
    • Silhouette and scale of Icarosaurus based on information in "The Triassic gliding reptile Icarosaurus" by Edwin H. Colbert
    • Silhouette and scale of Kuehneosaurus and Kuehneosuchus based on information in "THE AERODYNAMICS OF THE BRITISH LATE TRIASSIC KUEHNEOSAURIDAE" by KOEN STEIN, COLIN PALMER, PAMELA G. GILL, MICHAEL J. BENTON
    • Silhouette and scale of Xianlong based on information in "A gliding lizard from the Early Cretaceous of China" and Pi-Peng Li; Ke-Qin Gao; Lian-Hai Hou & Xing Xu
    • Hand and grids based on Adelophthalmus_Size.svg by Slate Weasel, released into the public domain
    Tail lengths of Kuehneosaurus, Kuehneosuchus and Mecistotrachelos are hypothetical, while those of Coelurosauravus and Weigeltisaurus are somewhat longer than the minimum length indicated by the preserved portion of the tails of these taxa
