Figure 2 in Sex estimation from morphology in living animals and dinosaurs

Figure 2. Five types of dimorphism expression observed, with exemplar species. For each species, a biplot of DVP and a histogram of the most bimodal metric is given, except for Cyperideis torosa, for which two additional plots, of PCAll 1–2 and PCDVP 1–2, are also provided to demonstrate sex-wise correlations in these variable pairs. A–D, Type 1; E–H, Type 2; I, J, Type 3; K–N, Type 4; O, P, Type 5, Q–T, Type 1'. Species are: A, B, Seminatrix pygae; C, D, Homarus gammarus; E, F, Mus musculus; G, H, Parus major; I, J, Gymnorhamphichthys rondoni; K, L, Anolis hendersoni; M, N, Longiperna concolor; O, P, Panthera leo; Q, T, Cyperideis torosa. Blue is male and red is female (true sex).
