Bivariate plot of two axes of the NMMDS analysis of a GDA dissimilarity matrix of the geometry of the pubic peduncle of the ilium of 52 iguanodontoidean specimens. Each dot is surrounded by the outline (rotated 90º) of the pubic peduncle of the specimen that it represents. Colors indicate the following groups: green = non-hadrosaurid Iguanodontoidea; blue = non-lambeosaurine Hadrosauridae; red = Lambeosaurinae; yellow = Hadrosauridae indeterminate. The inserted smaller plot shows the Bayesian Information Criterion (BIC) for various numbers of clusters in which the data may be classified. Abbreviations in the BIC plot are as in Fig. F.4.
