Abstract

Abstract 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, splenial, 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.

草甘膦Scoloparia glyphanodon的牙齿植入和附着（副爬行动物：原牙形目）

摘要我们描述了在一个钩吻Scoloparia glyphanodon标本中的牙齿植入、替换和附着。尽管早期对该标本的描述提到了齿状、脾状和冠状，但我们发现了一小部分也存在的棱角。我们观察到两种牙齿植入模式（原牙周和顶牙周），并且没有更换牙齿，尽管随着时间的推移，牙齿很可能是后植入的。先前对直发性息肉的牙齿植入的解释与置换模式和植入方式混为一谈。此外，该标本的牙齿特征组合表明，Scoloparia glyphanodon有草食性饮食。
