Abstract

‘Captorhinikos’ chozaensis Olson, 1954 is a captorhinid eureptile with multiple tooth rows from the lower Permian (Cisuralian: Kungurian) Clear Fork Group of north-central Texas and the Hennessey Formation of Oklahoma. It has five maxillary and four dentary tooth rows. We re-examined the available specimens referred to ‘Captorhinikos’ chozaensis to elucidate aspects of its skeletal structure and assess its phylogenetic relationships. Our parsimony analysis confirmed previous suggestions that this taxon is not referable to the same taxon as Captorhinikos valensis Olson, 1954 (type species of the genus) and ‘Captorhinikos’ parvus Olson, 1970 and thus is placed in its own new genus, Sumidadectes. It also recovered Sumidadectes chozaensis n. comb. as the earliest-diverging moradisaurine captorhinid. UUID: http://zoobank.org/0f89869a-1889-4d90-b721-a89ba5f40c4b

重新评估俄克拉荷马州和德克萨斯州中北部早二叠世（西苏拉世：昆古里亚）的 "Captorhinikos "chozaensis爬行动物

Captorhinikos' chozaensis Olson, 1954 是德克萨斯州中北部二叠纪下统（Cisuralian：Kungurian）Clear Fork 组和俄克拉荷马州 Hennessey Formation 中的一种具有多排牙齿的捕食龙类。它有五个上颌齿列和四个齿列。我们重新研究了现有的被称为 "Captorhinikos "chozaensis的标本，以阐明其骨骼结构的各个方面并评估其系统发育关系。我们的解析分析证实了之前的建议，即这一分类群不能与 Captorhinikos valensis Olson, 1954（该属的模式种）和 'Captorhinikos' parvus Olson, 1970 归为同一分类群，因此应将其归入自己的新属 Sumidadectes。它还恢复了 Sumidadectes chozaensis n. comb.，使其成为最早分化的 moradisaurine captorhinid。UUID: http://zoobank.org/0f89869a-1889-4d90-b721-a89ba5f40c4b

期刊介绍： Accounts of Chemical Research presents short, concise and critical articles offering easy-to-read overviews of basic research and applications in all areas of chemistry and biochemistry. These short reviews focus on research from the author’s own laboratory and are designed to teach the reader about a research project. In addition, Accounts of Chemical Research publishes commentaries that give an informed opinion on a current research problem. Special Issues online are devoted to a single topic of unusual activity and significance. Accounts of Chemical Research replaces the traditional article abstract with an article "Conspectus." These entries synopsize the research affording the reader a closer look at the content and significance of an article. Through this provision of a more detailed description of the article contents, the Conspectus enhances the article's discoverability by search engines and the exposure for the research.
