Boxplot showing the distribution of the ratio between the length of the distal expansion of the ischium and that of the ischial shaft 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 variables of this ratio were measured, exemplified in a ischium of Lambeosaurus laticaudus (LACM 17715). Horizontal lines delimit character states.
