ABSTRACT

We describe a new fossil species of Ceratophrys from cave sediments in Brazil tentatively assessed as late Pleistocene–early Holocene in age. The specimen consists of a nearly complete skull that is missing only the right premaxilla and the right columella. A detailed description and comparative analysis, which considers both living and fossil species, supports the conclusion that the specimen represents a previously unknown, extinct species of Ceratophrys. Poorly represented and assessed characters, paleodistribution of Ceratophryidae, and the taxonomic rectification of the Ceratophrys fossil specimens described by Günther (1859 Günther, A. C. L. G. 1859. Sexual differences found in bones of some Recent and fossil species of frogs and fishes. Annals and Magazine of Natural History 3:1–13. [Google Scholar]) are also discussed.

摘要

我们从巴西的洞穴沉积物中描述了一种新的陶粒化石，暂定为晚更新世-早全新世。标本由几乎完整的头骨组成，仅缺少右前颌骨和右小柱。详细的描述和比较分析同时考虑了活体和化石物种，支持以下结论：该标本代表了以前未知的，灭绝的角柏科物种。代表不力和评估的特征，角鳞科的古分布和古特尔（1859年）描述的角棘科化石标本的分类学校正 冈瑟（ACLG 1859）。在某些新近的青蛙和鱼的化石骨骼中发现性别差异。志和自然历史3的杂志：1 - 13。 [Google Scholar]）也进行了讨论。
