Figure 3 in Reinvestigation of Protelytron permianum (Insecta; Early Permian; USA) as an example for applying reflectance transformation imaging to insect imprint fossils

Figure 3. Template for assembly of operative models of right fore- and hind wing reconstructions of Protelytron permianum Tillyard, 1931. Dorsal (a) and ventral (b) views. See text for abbreviations and colour coding, and Béthoux et al. (2016) for a video tutorial. Assembly instructions: print the whole figure and fold along the grey dashed line; glue inner sides of paper sheet together; cut out wings along their outlines; in the hind wing, imprint the folds with a needle and a ruler; imprint concave folds (purple) on the dorsal side; imprint convex folds (green, orange, and blue) on ventral side; and imprint red fold weakly on both sides. To assist colour-blind readers, folds should be imprinted where represented by a full-colour full line (as opposed to a pale-colour dash-dotted line).
