Figure 4 in Global phylogeny of Hadrosauridae (Dinosauria: Ornithopoda) using parsimony and Bayesian methods
Figure 4. Bayesian information criterion (BIC) plots resulting from the clustering model analysis implemented in Mclust (within the R statistical package). A, BIC plot of two clustering models for a one-dimensional data set (i.e. a character quantified with a linear measurement). B, BIC plot for various clustering models of NMMDS derived from a geodesic distance analysis (GDA) dissimilarity matrix. Indentifiers of clustering models indicate the type of distribution (spherical, diagonal, or ellipsoidal), volume (equal or variable), shape (equal or variable), and orientation (not applicable, coordinate axes, equal, or variable) of the clusters: EEE = ellipsoidal, equal volume, shape and orientation; EEI = diagonal, equal volume, variable shape; EEV = ellipsoidal, equal volume and shape, variable orientation; EII, spherical, equal volume and shape; EVI = diagonal, equal volume, variable shape; VEI = diagonal, variable volume, equal shape; VEV = ellipsoidal, variable volume, equal shape; VII, spherical, variable volume, equal shape; VVI = diagonal, variable volume and shape; VVV = ellipsoidal, variable volume and shape (Fraley & Raftery, 2003).
Figure 5 in Global phylogeny of Hadrosauridae (Dinosauria: Ornithopoda) using parsimony and Bayesian methods
Figure 5. Strict consensus tree of the 160 most parsimonious trees resulting from the parsimony analysis of 53 iguanodontian taxa. At each node, the pair of numbers separated by a slash above a branch represents, from left to right, a decay index and a bootstrap proportion. Bootstrap proportions lower than 50 are indicted by a hyphen. The decimal number in italics that appears below a branch represents the P value of topology-dependant permutation tail probability (T-PTP) analysis.
Figure 6 in Global phylogeny of Hadrosauridae (Dinosauria: Ornithopoda) using parsimony and Bayesian methods
Figure 6. Strict reduced consensus tree of the 160 most parsimonious trees resulting from the parsimony analysis of 53 iguanodontian taxa. Posterior to the analysis, Claosaurus agilis, Barsboldia sicinskii, and Nipponosaurus sachalinensis were pruned from the data after implementation of REDCON 3.0 (Wilkinson, 2001b). At each node, the pair of numbers separated by a slash above or below a branch represents, from left to right, a decay index and a bootstrap proportion. Bootstrap proportions lower than 50 are indicted by a hyphen. The decimal number in italics that appears below a branch represents the P value of topology-dependant permutation tail probability (T-PTP) analysis.

The vertical white arrow indicates the position of the ventral apex of the supraacetabular crest relative to the posteroventral corner (black arrow) of the posterior tuberosity of the ischial peduncle. (b) Line drawing of the right ilium of YPM 1190 showing in gray the areas with plaster reconstruction.

FIGURE 3 in Revised diagnoses of Hadrosaurus foulkii Leidy, 1858 (the type genus and species of Hadrosauridae Cope, 1869) and Claosaurus agilis Marsh, 1872 (Dinosauria: Ornithopoda) from the Late Cretaceous of North America
FIGURE 3. Distribution, in a phylogenetic context, of the relative length and profile of the laterodistal corner of the deltopectoral crest of the humerus, and the anteroposterior width of the supraacetabular crest and position of its apex relative to the ischial peduncle of the ilium in Hadrosaurus foulkii and selected major groups of iguanodontian dinosaurs. The cladogram has been simplified from the strict reduced consensus tree presented by Prieto-Márquez (2010). From left to right, specimens used as clade or taxon representatives are as follows. Non-hadrosauroid Iguanodontia: skull of Iguanodon bernissartensis (IRSNB 1731), and right humerus (NHMUK R6616; reversed) and left ilium (NHMUK 11521) of Mantellisaurus atherfieldensis. Nonhadrosaurid Hadrosauroidea: skull of Equijubus normani (IVPP V12534), and right humerus (AMNH 30728; reversed) and right ilium (AMNH 30735; reversed) of Gilmoreosaurus mongoliensis. Hadrosaurus foulkii: line drawing of the historical skull model sculpted by Waterhouse Hawkins, and left humerus and left ilium of ANSP 10005. Saurolophinae: skull of Edmontosaurus annectens (SM R4036) and left humerus of Gryposaurus latidens (AMNH 5465). Lambeosaurinae: skull of Parasaurolophus walkeri (ROM 768) and left humerus of P. cyrtocristatus (FMNH P27393). The right ilium (reversed) representing both saurolophines and lambeosaurines (i.e., Saurolophidae) is that of Brachylophosaurus canadensis (MOR 794). Skulls and ilia are shown in left lateral view; humeri are displayed in anteromedial view.
