3D plot of three axes of the NMMDS analysis of a GDA dissimilarity matrix of the geometry of the prepubic process of the pubis for 36 iguanodontoidean specimens. Each dot is surrounded by the outline of the preacetabular process of the specimen that it represents. Colors indicate the following groups: green = non-hadrosaurid Iguanodontoidea; blue = non-lambeosaurine Hadrosauridae; red = Lambeosaurinae; yellow = Hadrosauridae indeterminate. Pubic profiles for each point are facing rostrolaterally towards the reader. 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.
