Boxplot showing the distribution of the position of the dorsal process and the dorsal margin of the dorsolateral eminence of the maxilla 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 maxilla of Gryposaurus sp. (MOR 553S-8-26-9-55).
