Boxplot showing the distribution of the ratio between the depth of the central plate of the ilium and the distance between the pubic peduncle and the caudodorsal prominence of the ischial peduncle, for a sample of iguanodontoidean ornithopods. The inserted smaller graph shows the Bayesian information criterion (BIC) for various numbers of clusters in which the data can be classified. The photograph shows how the two variable of this ratio were measured, exemplified in the ilium of Secernosaurus koerneri (MACN-RN 2). Grey horizontal lines delimit character states.
