Ancestral character state reconstructions of the 34 braincase characters from Maddin et al. [28] for the condition at the base of extant caecilians and a comparison with the condition seen in Eocaecilia micropodia.

Ancestral character state reconstructions of the 34 braincase characters from Maddin et al. [28] for the condition at the base of extant caecilians and a comparison with the condition seen in Eocaecilia micropodia.针对Maddin等人[28]报道的34项脑颅特征（braincase characters），开展现生蚓螈基部类群性状状态的祖先特征状态重建（Ancestral character state reconstructions），并与小足始蚓螈（Eocaecilia micropodia）的对应性状状态进行对比。
