摘要：本文描述了原始石炭纪波希米诺端椎龙的颅骨解剖结构，来自几个大型的、可能是成年的头骨。这一新的形态学数据修改了 Frič（= 1876 年后出版物中的 Fritsch）、Romer 和 Steen 的早期描述，这些描述几乎完全基于小型、亚成体波西米利耳龙标本。波希米亚耳蜗龙的新自体变态（眼眶后腹侧表面的凹陷）的识别与个体发育变化无关，促进了耳蜗龙科之间更准确的种内比较。分支分析揭示了明显的二分法，将 Edopoidea 与剩余的 temnospondyls 的更衍生的分支（包括 Balanerpeton 和 Dendrerpeton）分开。在此分析中，Edopoidea 作为一个总科的支持很弱。内甲龙科是一个单系科，包括原甲龙属、金刚甲龙属、内甲龙属和藜属。
ABSTRACT The cranial anatomy of the primitive Carboniferous temnospondyl Cochleosaurus bohemicus is described herein from several large, presumably adult, skulls. This new morphological data modifies earlier descriptions by Frič (=Fritsch in post-1876 publications), Romer and Steen, which were based almost entirely on small, subadult Cochleosaurus bohemicus specimens. Recognition of a new autapomorphy for Cochleosaurus bohemicus, (pitting on the ventral surface of the postorbitals) which is independent of ontogenetic change, has facilitated more accurate intra-specific comparisons between cochleosaurids. Cladistic analysis reveals a clear dichotomy separating the Edopoidea from the more derived clade of the remaining temnospondyls, which includes Balanerpeton and Dendrerpeton. The Edopoidea are only weakly supported as a superfamily in this analysis. The Cochleosauridae are a monophyletic family comprising the genera Procochleosaurus, Adamanterpeton, Cochleosaurus and Chenoprosopus.
