Boxplot showing the distribution of the ratio between the dorsoventral depth of the distal end of the scapular blade and the depth of the proximal region of the scapula 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 Lambeosaurus lambei (ROM 1218). Grey horizontal lines delimit character states.
