我们描述了牙齿种植，更换，并附着在标本的原colophonia猪头。虽然标本的早期描述提到了齿状、棘状和冠状，但我们确定了角状的一小片也存在。我们观察到两种模式的牙齿种植（原齿和肩齿）和没有牙齿更换，尽管很可能随着时间的推移，牙齿被添加到后面。先前对原树脂体牙种植的解释与替代模式和种植模式相混淆。此外，该标本的牙齿特征表明，猪头螺是食草动物。
We describe tooth implantation, replacement, and attachment in a specimen of the procolophonid Scoloparia glyphanodon. Though an earlier description of the specimen made mention of the dentary, splcnial, and coronoid, we identify a small sliver of the angular that is also present. We observe two modes of tooth implantation (protothecodonty and acrodonty) and no tooth replacement, though it is likely teeth were added posteriorly over time. Previous interpretations of tooth implantation in procolophonids were conflated with replacement patterns and mode of implantation. Additionally, the combination of dental characters of the specimen suggests Scoloparia glyphanodon had an herbivorous diet.
