Boxplot showing the distribution of the ratio between the dorsoventral depth of the proximal region of the
scapula and its craniocaudal length 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 a scapula of Secernosaurus koerneri (MACN-RN 142). Grey horizontal lines delimit character states.
