摘要

古代干蝾螈（Karauridae的中侏罗世-早白垩世代表）具有两个钙化中心和一个弱矿化分隔带的带蒂（亚带蒂）齿。亚蒂齿的存在，现代蝾螈幼虫后期的典型特征，证实了干蝾螈的新生期性质。在干蝾螈和干无尾螈中存在的带蒂牙齿证实了带蒂牙齿是现代两栖动物群的一种近亲的假设，相应地，也证实了单系两栖动物的假设。

Pedicellate Teeth in Archaic Salamanders (Lissamphibia, Caudata).

The presence of pedicellate (subpedicellate) teeth with two calcification centers and a weakly mineralized dividing zone is described for archaic stem salamanders (Middle Jurassic-Early Cretaceous representatives of Karauridae). The presence of subpedicellate teeth, typical of the late larval stage of modern salamanders, confirms the neotenic nature of stem salamanders. The presence of pedicellate teeth in stem salamanders and stem caecilians confirms the hypothesis of pedicellarity as a synapomorphy of modern amphibian groups and, accordingly, the monophyly of Lissamphibia.
