Fig. 5. Photograph and interpretive drawing of the positive cast of GMV-2159. The study of GMV-2159 was based on a positive cast of epoxy resin, which renders greater anatomical details. This positive cast was molded from a positive cast of RTV (room temperature vulcanizing) silicon rubber made from the natural mold (fig. 4). Abbreviations: d, dentary; mad, major digit; pyg, pygostyle; scl, sclerotic; I–IV, pedal digits I– IV; (l) or (r), left or right element. Other abbreviations as in figure 3.
