Boxplot showing the distribution of the ratio between the proximal slope of the dentary edentulous portion and the length of the dental battery in a sample of iguanodontoidean taxa. 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 Corythosaurus casuarius (CMN 8676). Grey horizontal lines delimit character states.
