Comments
Boxplot showing the distribution of the ratio between the length of the narial foramen and the distance between the rostroventral corner of the premaxilla and the rostroventral margin of the prefrontal 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 the skull of Gryposaurus notabilis (CMN 2278).
Grey horizontal lines delimit character states.
