对小型鸟臀目恐龙原角龙的褶边和牙突进行了异速测量。对37个标本的分析，包括四种不同的大小类别的动物，表明褶边（在长度和宽度上）在个体发育过程中经历了正异速生长，而小腹也显示出相对大小增加的趋势。结合其他数据，这支持了这些特征是作为社会性别优势信号在选择下形成的。
The allometry in the frill and jugal bosses of the small ornithischian dinosaur Protoceratops andrewsi are assessed. An analysis of 37 specimens, encompassing four distinct size classes of animal, shows that the frill (in both length and width) undergoes positive allometry during ontogeny, while the jugals also show a trend towards an increase in relative size. In conjunction with other data, this provides support that these features were under selection as socio-sexual dominance signals.
