RMA regressions of radius length against width.

<p>A–B, radius length against anteroposterior width; A, regression lines of Stegosauria, Ankylosauria, Hadrosauridae, Ceratopsidae and basal bipedal ornithischians; B, regression lines of Thyreophora, Ornithopoda and Marginocephalia. C, radius length against mediolateral width. Regression lines for groups in which there was no statistically significant correlation between X and Y at the p = 0.05 level are not shown. Abbreviations: <b>RAPW</b>, radius anteroposterior width; <b>RL</b>, radius length; <b>RMLW</b>, radius mediolateral width.
