Abstract: The histological characteristics of Granatodontus, one of the most primitive euconodont elements, is mainly discribed. The structures of Granatodontus is very similar to that of Proconodontus muelleri, another kind of euconodont elements presented much earlier, too. The result shows that histology study is of great taxonomic significance, especially for the primitive euconodont elements.

Key words: Primitive euconodonts, Granatodontus, histological study

摘要: 以原始真牙形石分子 Granatodontus 属的研究为例,描述了该类分子的组织学特征。并与另一种早期的真牙形石分子 Proconodontus muelleri 进行了对比,二者的内部构造非常相似,都具有原始真牙形石的特征。研究结果表明,组织学方法在原始真牙形石的分类研究中具有重要的分类学意义。
