Boxplot showing the distribution of the ratio between the dorsoventral depth and the breadth of the ventral process of the coracoid 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 raio were measured, exemplified in an indeterminate hadrosaurid coracoid (TMP 92.36.983). Grey horizontal lines delimit character states.
